Application of polyurethane TPE anti-yellowing agent in surface treatment of household appliances

1. Introduction: Make home appliances “face” brighter

In today’s era of “appearance is justice”, the appearance design of household appliances has long become one of the important considerations for consumers’ purchases. Just imagine, if a brand new refrigerator or washing machine has an embarrassing yellow spot on the surface after long-term use, its original high-end temperament will be greatly reduced in an instant. We call this phenomenon “yellow change”. In order to deal with this problem, polyurethane TPE anti-yellowing agent came into being and became a star product in the field of modern home appliance surface treatment.

So, what is polyurethane TPE anti-yellowing agent? Simply put, this is an additive specially used to improve the aging resistance of materials. Its main function is to delay or prevent material color changes caused by factors such as ultraviolet irradiation and high temperature oxidation. For household appliances, whether it is a plastic shell or a coated surface, once it turns yellow, it will not only affect the beauty, but may also reduce the service life and market competitiveness of the product. Therefore, how to improve the anti-yellowing performance of home appliance surfaces through scientific means has become a key topic of concern to the industry.

This article will start from the basic principles of polyurethane TPE anti-yellowing agent and combine practical application cases to deeply explore its important role in the surface treatment of household appliances. At the same time, we will use easy-to-understand language, supplemented by detailed data tables and document references to help readers fully understand the charm of this technology. Next, let us unveil this mysterious veil of protecting the “face” of home appliances!

2. Characteristics and working principle of polyurethane TPE anti-yellowing agent

(I) Definition and classification of polyurethane TPE anti-yellowing agent

Polyurethane TPE anti-yellowing agent is a functional chemical additive that is widely used in thermoplastic elastomer (TPE) materials, aiming to reduce or eliminate material color deterioration caused by environmental factors. Depending on its chemical structure and mechanism of action, this type of anti-yellowing agent can be divided into the following categories:

UV Absorbent Anti-Yellowing Agent
This type of anti-yellowing agent can effectively absorb UV energy and convert it into harmless heat to release it, thereby avoiding the damage of UV light to the material’s molecular bonds. Common UV absorbers include benzotriazoles, salicylates, etc.
Free radical capture anti-yellowing agent
Under light or high temperature conditions, free radicals are easily generated inside the material, which will accelerate the aging process of the material. Free radical capture anti-yellowing agents can capture free radicals through chemical reactions, inhibiting the occurrence of chain reactions, thereby achieving the effect of delaying yellowing.
Antioxidation-type anti-yellowing agent
Such anti-yellowing agents mainly target the oxidation reaction of the material in a high temperature environment, interrupting the oxidation reaction chain by providing hydrogen atoms or other active substances, thereby protecting the material from damage.
Compound anti-yellowing agent
Compound anti-yellowing agent combines the advantages of the above functions, can exert synergistic effects in different environments, and is suitable for high-performance needs under complex operating conditions.

(II) Working principle of anti-yellowing agent

The key reason why polyurethane TPE anti-yellowing agent can effectively prevent the material from yellowing is its unique chemical structure and mechanism of action. Here is a brief description of its main working principle:

Ultraviolet shielding
The UV absorbing components in the anti-yellowing agent can preferentially absorb high-energy ultraviolet rays and convert them into low-energy infrared or visible light, thereby avoiding the ultraviolet rays acting directly on material molecules, causing molecular bond breakage and degradation.
Free radical scavenging
When the material is exposed to high temperatures or strong light, a large amount of free radicals may be generated inside the molecules. If these free radicals are not removed in time, they will trigger a chain reaction, which will eventually cause the material to discolor or even crack. Anti-yellowing agents quickly neutralize free radicals by providing electrons or hydrogen atoms, thereby preventing further chemical reactions.
Antioxidant protection
Oxidation reaction in high temperature environments is one of the main reasons for material yellowing. Anti-yellowing agents provide a stable antioxidant environment for the material by sacrificing its own molecular structure and extending the service life of the material.

(III) Product parameters list

In order to better understand the performance characteristics of polyurethane TPE anti-yellowing agent, we have compiled a detailed product parameter list as follows:

parameter name	Unit	Typical value range	Description
Density	g/cm³	1.05 – 1.20	Denotes the mass per unit volume of the material, affecting processing fluidity and molding performance
Thermal Stability	℃	>280	The material’s tolerance under high temperature conditions ensures that it does not decompose long-term use
UV absorption efficiency	%	≥95	The ability to absorb ultraviolet rays, the higher the value, the better the protection effect
Free radical scavenging rate	%	≥80	The ability to scavenge free radicals directly affects the anti-yellowing effect
Solution	——	Easy soluble in organic solvents	Easy to mix with other materials and improve processing adaptability
Additional amount	%	0.5 – 2.0	Adjust the addition ratio according to the specific application scenario. Too much may lead to other performance degradation

The above parameters are only general reference values, and the specific values may vary depending on the supplier and production process. In practical applications, it is necessary to optimize the selection based on the characteristics of the target material and the use environment.

III. Practical application of polyurethane TPE anti-yellowing agent in household appliances

(I) Analysis of the causes of yellowing of household appliances

As an indispensable part of daily life, household appliances usually need to have good wear resistance, corrosion resistance and aesthetics. However, during long-term use, due to the influence of the external environment, many home appliances will experience varying degrees of yellowing on the surface. Here are some common causes of yellowing:

Ultraviolet radiation
When the appliance shell or panel is exposed to sunlight for a long time, ultraviolet rays will destroy the molecular structure of the material, causing molecular bonds to break, thereby causing color changes.
High temperature aging
Kitchen appliances such as microwave ovens, ovens, etc. are often in high temperature environments, which will cause the material to undergo oxidation reaction and then yellowing.
Chemical erosion
Some detergents or airborne contaminants can react chemically with appliance surface materials to form yellow deposits that are difficult to remove.
Mechanical Stress
Frequent physical friction or impact may also cause changes in the surface molecular structure of the material, thereby accelerating the yellowing process.

(II) Application cases of anti-yellowing agents

In order to effectively solve the above problems, polyurethane TPE anti-yellowing agents are increasingly widely used in household appliances. The following are some typical application scenarios:

1. Refrigerator housing

As one of the most frequently used electrical appliances in the home, the refrigerator is mostly made of ABS or PC/ABS alloys. Although these materials have excellent mechanical properties, they are susceptible to the influence of ultraviolet rays and oxygen during long-term use and yellowing. By adding an appropriate amount of polyurethane TPE anti-yellowing agent, the anti-aging performance of the refrigerator shell can be significantly improved and keep it as bright as new.

2. Microwave oven door panel

Microwave oven door panels are usually made of transparent or translucent polycarbonate (PC) materials, which are prone to yellowing in high temperature environments, affecting the visual effect. Experiments show that after adding a specific proportion of UV-absorbing anti-yellowing agent, the light transmittance and color stability of the door panel were significantly improved.

3. Vacuum cleaner handle

The vacuum cleaner handle is mostly made of soft TPE material to provide a comfortable grip experience. However, this material is also prone to discoloration due to friction and oxidation during long-term use. By introducing free radical capture anti-yellowing agent, it can not only extend the service life of the handle, but also enhance user satisfaction.

(III) Current status of domestic and foreign research

In recent years, significant progress has been made in the research on polyurethane TPE anti-yellowing agents. For example, DuPont, the United States, has developed a new composite anti-yellowing agent, whose comprehensive performance is far beyond that of traditional single-function products; while BASF, Germany, focuses on the research and development of environmentally friendly anti-yellowing agents, striving to reduce the impact on the environment while ensuring the effect.

In China, a study from the Department of Chemical Engineering of Tsinghua University showed that by adjusting the molecular structure of anti-yellowing agents, selective regulation of their absorption wavelength can be achieved, thereby better adapting to the needs of different materials. In addition, the School of Materials Science and Engineering of Zhejiang University proposed a nanotechnology-based anti-yellowing solution. This solution further enhances the anti-yellowing effect by constructing a nano-level protective layer on the surface of the material.

Analysis of economic benefits of KPU-specific anti-yellowing agents, reduce production costs and increase corporate profits

KPU-specific anti-yellowing agent: economic benefit analysis and cost optimization

In today’s highly competitive chemical market, if companies want to break out in the red ocean, they must find a good balance between product quality and production cost. KPU (polyurethane) is a widely used polymer material, plays an indispensable role in automotive interiors, electronics and appliances, furniture manufacturing and other fields. However, KPU products are prone to yellowing during long-term use, which not only affects the appearance of the product, but also may reduce its performance stability, thereby affecting consumers’ willingness to purchase. Therefore, how to effectively prevent the yellowing of KPU products has become a technical problem that many manufacturers need to solve urgently.

To meet this challenge, KPU-specific anti-yellowing agents came into being. This highly efficient additive can not only significantly delay the yellowing rate of KPU products, but also maintain its original physical properties and mechanical strength, bringing considerable economic benefits to the enterprise. This article will deeply explore the application value of KPU-specific anti-yellowing agents from multiple dimensions, including its product parameters, production process optimization, cost saving potential and positive impact on corporate profits, and conduct detailed analysis based on relevant domestic and foreign literature data. At the same time, the article will also explain through specific cases how to further improve the efficiency of anti-yellowing agents through scientific management, so as to help enterprises occupy an advantageous position in market competition.

Basic characteristics and mechanism of KPU-specific anti-yellowing agent

Product definition and function overview

KPU-specific anti-yellowing agent is a highly efficient stabilizer specially designed for polyurethane materials. It mainly delays or prevents the yellowing of KPU products under light, high temperature and other conditions by inhibiting photochemical reactions and oxidation reactions. This additive not only protects the color of the material’s surface, but also maintains the integrity of its internal structure, thereby extending the service life of the product. According to its mechanism of action, anti-yellowing agents can be divided into three categories: ultraviolet absorption type, free radical capture type and antioxidant type. Among them, the ultraviolet absorption anti-yellowing agent converts it into heat energy by absorbing ultraviolet energy, thereby reducing the damage to the KPU molecular chain by ultraviolet rays; the free radical capture type blocks the propagation of chain reactions by capturing active free radicals generated during the reaction; while the anti-oxidation type fundamentally inhibits the occurrence of yellowing by-products caused by oxygen molecules.

Core components and technical features

The core components of KPU-specific anti-yellowing agents are usually composed of benzotriazoles, hydroxybenzones and hindered amine compounds, which have excellent photostability and thermal stability. The following are its main technical features:

High efficiency: Even at extremely low additions (usually 0.1%-0.5%), the anti-yellowing performance of KPU products can be significantly improved.
Compatibility: It has good compatibility with various types of KPU materials and will not affect the original performance of the material.

Weather Resistance: Can maintain stability for a long time in extreme environments, suitable for outdoor and harsh working conditions.

Environmentality: Comply with international environmental standards, non-toxic and harmless, and friendly to the human and environmentally.

Application Fields and Market Demand

As consumers continue to increase their product quality requirements, the demand for KPU-specific anti-yellowing agents is also increasing year by year. Its main application areas include but are not limited to the following aspects:

Auto Industry: Used for interior parts such as instrument panels, steering wheels, seat covers, etc., to ensure that the vehicle remains bright and new after long-term use.

Electronics: Applied to electronic components such as TV housing, computer keyboard, mobile phone case, etc., to improve the durability and aesthetics of the product.

Home Decoration: Used for soft furniture such as sofas, mattresses, curtains, etc., to meet the requirements of modern families for high-quality life.

According to new market research data, the global KPU-specific anti-yellowing agent market size has exceeded US$2 billion, and it is expected to continue to grow at an average annual rate of 8% in the next five years. This trend shows that anti-yellowing agents are not only an important tool to ensure product quality, but also a key factor in promoting industrial upgrading.

Cost-benefit analysis of KPU-specific anti-yellowing agent

Cost composition and input-output ratio

When evaluating the economic benefits of KPU-specific anti-yellowing agents, we first need to clarify its cost composition. Generally speaking, the total cost of anti-yellowing agent can be divided into three parts: raw material procurement cost, processing and processing cost, and logistics and transportation expenditure. Taking KPU products per ton of KPU products as an example, assuming that the addition ratio of anti-yellowing agent is 0.3%, the anti-yellowing dose required per ton of product is about 3 kg. Calculated according to the current market price, the unit price of high-quality anti-yellowing agent is about 30 yuan/kg, so the direct material cost per ton of product increases by about 90 yuan.

However, this seemingly small cost investment can bring significant returns. Studies have shown that after using anti-yellowing agents, the service life of KPU products can be extended by at least 30%, while the return rate and rework rate have decreased by more than 50% respectively. This means that the company’s expenditure on after-sales maintenance has been greatly reduced, and indirectly saving a lot of human and material resources. In addition, anti-yellowing agents can significantly improve productionThe appearance quality of the product and customer satisfaction also improve, thereby promoting sales growth. It is estimated that the comprehensive benefits per ton of product due to the use of anti-yellowing agents can reach more than 600 yuan, far exceeding its initial investment cost.

Comparative analysis of financial indicators

In order to more intuitively demonstrate the economic value of anti-yellowing agents, we can compare and analyze the following key financial indicators:

Indicator Name Pre-use value Value after use Percentage of growth

Unit Production Cost 5000 yuan/ton 5090 yuan/ton +1.8%

Average Sales Price 7000 yuan/ton 7200 yuan/ton +2.9%

Net profit margin 20% 25% +25%

Investment recovery cycle 3 years 2.4 years -20%

From the above table, it can be seen that although the unit production cost has increased slightly, the overall profitability of the company has been significantly enhanced due to the increase in sales prices and the significant improvement in profit margins. More importantly, the shortening of the investment recovery cycle provides enterprises with stronger capital turnover capabilities, allowing them to invest faster in new technology research and development and market expansion.

Long-term strategic significance

In addition to short-term economic benefits, the introduction of KPU-specific anti-yellowing agents has important long-term strategic significance. First of all, it can help companies establish differentiated competitive advantages and establish a high-end brand image. This is particularly important in an increasingly homogeneous market competition environment. Secondly, the application of anti-yellowing agents helps reduce energy consumption and waste emissions, conforms to the concept of sustainable development, and has also won more policy support and social recognition for enterprises. Later, by accumulating rich application experience and technical reserves, enterprises can launch more innovative products and services in the future, further consolidating their industry leadership.

To sum up, although the initial investment cost of KPU-specific anti-yellowing agents is relatively high, in the long run, the economic benefits it brings far exceeds this threshold. As the saying goes, “I can’t bear to leave my children and can’t catch the wolf.” Only companies that dare to invest can remain invincible in future market competition.

Production process optimization strategy for KPU special anti-yellowing agent

In modern chemical production, optimization of process flow is a key link in reducing costs and improving efficiency. For KPU-specific anti-yellowing agents, the improvement of its production process not only affects the stability of product quality, but also directly affects the company’s production costs and profit margins. Below we will introduce in detail how to optimize the production of anti-yellowing agent through scientific management from multiple perspectives such as raw material selection, equipment configuration, and operating specifications.

Raw material selection and proportion optimization

The core components of anti-yellowing agents mainly include three categories: ultraviolet absorbers, free radical trapping agents and antioxidants. The selection of each component requires strict screening and testing. For example, when choosing ultraviolet absorbers, benzotriazole compounds are highly favored for their excellent light stability and low volatility; while in terms of radical trapping agents, hindered amine compounds stand out for their efficient capture ability and good heat resistance. In order to achieve the best results, the ratio between the components also needs to be accurately calculated. According to experimental data, when the ratio of ultraviolet absorber to radical capture agent is controlled at around 1:1.5, the overall performance of the anti-yellowing agent is ideal.

In addition, the purity and particle size of the raw materials are also important factors affecting product quality. High-purity raw materials can not only ensure the stability of the product, but also reduce the impurity removal steps in subsequent processing, thereby reducing energy consumption and labor costs. As for particle size control, it needs to be adjusted according to the specific application scenario. Generally speaking, the smaller the particle size, the better the dispersion, but too fine particles may lead to agglomeration, which will affect the use effect. Therefore, it is recommended to control the particle size range between 0.5-2 microns, which can not only meet the dispersion needs without causing unnecessary waste.

Enhanced equipment configuration and automation level

Advanced production equipment is the hardware foundation for achieving efficient production. In the production process of anti-yellowing agent, stirring and mixing, grinding and dispersing and drying packaging are the three key links. Based on the characteristics of each link, we can take the following measures to optimize:

Agitation and Mixing: Using a twin-screw extruder instead of traditional single-screw equipment can not only improve the uniformity of the material, but also significantly shorten the mixing time. According to statistics, after using the twin-screw extruder, the mixing efficiency has been increased by nearly 30%, while the energy consumption has been reduced by about 15%.

Grinding and Dispersion: Introduce a nano-scale sand mill to accurately control the particle size at the submicron level. Although this equipment has a large initial investment, its excellent dispersion effect can greatly reduce the dosage of additives and thus dilute unit costs.

Dry Packaging: Using vacuum freeze-drying technology to replace conventional hot air drying can not only avoid high temperature sensitive to high temperaturesThe damage can also effectively maintain the original form of the product. At the same time, equipped with a fully automatic packaging system can greatly reduce manual intervention and improve production efficiency.

It is worth mentioning that with the advent of the Industry 4.0 era, intelligence and digitalization have become important directions for the transformation and upgrading of the manufacturing industry. By introducing IoT technology and big data analysis platforms, enterprises can monitor the operating status of production lines in real time, discover and solve potential problems in a timely manner, and ensure that the production process is always in a good state.

Absolute operating specifications and quality control system

No matter how good the equipment and raw materials are, high-quality products cannot be produced without strict operating specifications as a guarantee. To this end, we need to establish a sound quality control system, from the inspection of raw materials entering the factory to the inspection of finished products leaving the factory, every link must be closely linked and layer by layer.

Raw Material Inspection: Develop detailed acceptance standards, including appearance, purity, moisture content and other indicators to ensure that all raw materials entering the factory meet the requirements.

Production process monitoring: Install an online monitoring device to dynamically track key parameters such as temperature, pressure, and speed. Once abnormal conditions are found, alarm will be prompted immediately.

Finished product sampling: Random sampling inspection is carried out in accordance with national standards or industry standards, focusing on the inspection of core indicators such as the anti-yellowing performance, dispersion and storage stability of the product.

At the same time, it is also necessary to organize regular employee training to strengthen safety awareness and responsibility awareness to ensure that every operator is proficient in equipment operating procedures and emergency response methods. Only in this way can we truly achieve the “zero defect” production goal and create greater value for the company.

2. Basic principles and development history of anti-yellowing agents

As a functional additive, anti-yellowing agent is mainly based on the organic combination of chemical reaction mechanisms and physical protection mechanisms. At the chemical level, anti-yellowing agents effectively prevent the chain reaction of polymer materials under light and hot oxygen environments by capturing free radicals and decomposing peroxides, thereby delaying or avoiding the yellowing of the material. Specifically, such compounds usually contain hydroxybenzotriazoles, hindered amines or other functional groups with antioxidant properties that can selectively bind to the active substance that causes yellowing at the molecular level to form a stable chemical structure, thereby terminating the spread of adverse reactions.

From historical development, the research and development of anti-yellowing agents can be traced back to the mid-20th century. Early anti-yellowing agents were mostly simple compounds with single ingredients, such as phenolic antioxidants and ultraviolet absorbers, and their application range was relatively limited. With the rapid development of the polymer material industry, especially high performance such as polyurethane and polyolefinWith the popularity of materials, traditional anti-yellowing agents can no longer meet the increasingly stringent application needs. After entering the 21st century, composite anti-yellowing agents have gradually become the mainstream. This type of product has achieved better stability and wider application adaptability by collaborating with multiple functional components.

It is particularly worth mentioning that the development of nanotechnology and green chemistry in recent years have brought new breakthroughs to anti-yellowing agents. For example, by introducing nano-scale metal oxides or carbon-based materials, the ultraviolet shielding effect of the anti-yellowing agent can be significantly enhanced; while new anti-yellowing agents prepared with biodegradable raw materials provide important support for the development of environmentally friendly materials. This technological advancement not only improves the overall effectiveness of anti-yellowing agents, but also opens up new paths for it to achieve its Sustainable Development Goals.

This additive not only significantly improves the service life of automotive interior components, but also maintains its long-term bright colors and excellent physical properties.

This article will deeply explore the application and importance of polyurethane TPE anti-yellowing agent in automotive interiors, and reveal the secrets behind this technology in all aspects, from basic principles to actual effects, from market status to future trends. We will also help readers better understand new developments and technological breakthroughs in this field through detailed data analysis and example descriptions.

Basic concept of polyurethane TPE anti-yellowing agent

Polyurethane TPE anti-yellowing agent is a special chemical additive, mainly used to prevent the color change of polyurethane thermoplastic elastomers (TPEs) under prolonged exposure to ultraviolet light or other oxidation conditions. Such additives usually contain ingredients such as UV absorbers, antioxidants and light stabilizers that work together to protect the material from the outside environment.

Chemical composition

The core components of anti-yellowing agent include but are not limited to the following:

UV absorbers: such as benzotriazoles and benzophenone compounds, these substances can effectively absorb UV light and convert them into harmless heat.

Antioxidants: It is divided into chain antioxidants and hindered phenolic antioxidants. The former can interrupt the free radical chain reaction, while the latter provides long-term antioxidant protection.

Light Stabilizers: For example, hindered amine light stabilizers (HALS), which slow down the degradation process of the material by capturing free radicals.

Mechanism of action

The mechanism of action of anti-yellowing agents is mainly reflected in three aspects:

Ultraviolet protection: By absorbing ultraviolet rays, it reduces the damage to polyurethane molecules by ultraviolet rays.

Free Radical Capture: Antioxidants and light stabilizers are able to capture and neutralize free radicals, preventing them from triggering further chemical reactions.

Molecular structure stability: By forming stable chemical bonds with polyurethane molecules, the overall stability of the material is enhanced.

Application Fields

Although anti-yellowing agents are widely used in many fields, they are particularly prominent in automotive interiors. Because the internal environment of the car is complex, with both high temperature and strong ultraviolet rays, special protection measures are needed. Anti-yellowing agents perform well in such environments, ensuring that car interior parts such as dashboards, door panels, seats, etc. maintain their original color and texture during long-term use.

To sum up, polyurethane TPE anti-yellowing agent provides the necessary protection for the automotive interior through its unique chemical composition and mechanism of action, extends the service life of the product, and improves the overall experience of the user.

Detailed explanation of the working principle of polyurethane TPE anti-yellowing agent

The reason why polyurethane TPE anti-yellowing agent can play an important role in automotive interiors can be attributed to several key steps: ultraviolet absorption, free radical capture and molecular structure stability. Here is a detailed explanation of these steps:

Ultraviolet absorption

Ultraviolet rays are one of the main reasons for yellowing of the material. When ultraviolet rays irradiate on polyurethane TPE, electron transitions within the molecule are triggered, thereby triggering a series of chemical reactions. The UV absorber in the anti-yellowing agent absorbs ultraviolet energy and converts it into harmless heat to release it, avoiding the direct effect of ultraviolet rays on polyurethane molecules. This process is similar to putting a layer of “sunscreen” on the material, effectively reducing the damage to the material by ultraviolet rays.

Category Features

Benzotriazoles Absorption wavelength range is wide, suitable for a variety of plastics and coatings, with good durability and thermal stability.

Benzophenone Products that are highly absorbed by short-wave ultraviolet rays but are easy to decompose and are suitable for short-term use.

Free Radical Capture

Ultraviolet light can not only directly destroy the polymer chain, but also generate reactive oxygen radicals by excitating oxygen molecules. Once these free radicals are formed, they will trigger chain reactions like dominoes, which will eventually lead to aging and discoloration of the material. Antioxidants and light stabilizers in anti-yellowing agents are designed for this problem. They are able to actively capture and neutralize free radicals, interrupting this chain reaction. SpecificallyIt is said that antioxidants inactivate free radicals by donating hydrogen atoms or electrons; while light stabilizers convert free radicals into stable compounds by capturing them.

Category Function

Chalk antioxidants Fast interruption of free radical chain reaction, suitable for short-term protection needs.

Stealed phenolic antioxidants Provides long-term antioxidant protection and is suitable for materials that require long-term stability.

Stable molecular structure

In addition to external protection, anti-yellowing agents also enhance their stability by changing the internal structure of polyurethane molecules. Certain anti-yellowing agent components can form covalent bonds or other forms of chemical bonds with polyurethane molecules, making the entire molecular structure more tight and stable. This structural improvement helps resist the invasion of external environmental factors, thereby further delaying the aging process of the material.

In short, polyurethane TPE anti-yellowing agents work together through the above three main mechanisms – ultraviolet absorption, free radical capture and molecular structure stability – to provide comprehensive protection for automotive interior materials, ensuring that they can maintain their original color and performance in various environments.

Types and characteristics of polyurethane TPE anti-yellowing agent

When exploring the world of polyurethane TPE anti-yellowing agents, it is crucial to understand their different types and their respective properties. Depending on the function and chemical composition, anti-yellowing agents can be mainly divided into three categories: ultraviolet absorbers, antioxidants and light stabilizers. Each type has its own unique advantages and application scenarios.

Ultraviolet absorber

Ultraviolet absorbers are a type of anti-yellowing agent that directly fights against ultraviolet invasion. This type of substance can absorb the energy of ultraviolet rays and convert them into heat energy to release them, thereby protecting the polyurethane TPE from being destroyed by ultraviolet rays.

Type Main Ingredients Pros Disadvantages

Benzotriazoles Benzotriazole derivatives Efficiently absorb ultraviolet rays, wide range of applications High cost

Benzophenone Benzophenone and its derivatives High absorption efficiency and relatively low price Easy to decompose, which may cause yellowing on the surface of the material

Antioxidants

Antioxidants interrupt the oxidation reaction chain by capturing free radicals, thereby preventing aging and discoloration of polyurethane TPE. They are particularly important for car interiors that are exposed to the air for a long time.

Type Main Ingredients Pros Disadvantages

Chalk antioxidants Phosphate compounds Respond quickly, with obvious immediate effect Poor durability

Stealed phenolic antioxidants Plurihydroxyaromatic compounds Long-term protection, good stability The initial effect is not as significant as that of chain antioxidants

Light stabilizer

Light stabilizers, especially hindered amine light stabilizers (HALS), act by capturing free radicals and converting them into stable nitrogen oxygen radicals, greatly delaying the photodegradation process of the material.

Type Main Ingredients Pros Disadvantages

HALS Trumped amine compounds Extremely strong light stabilization effect, suitable for a variety of plastics High cost and may be incompatible with certain materials

The above types of anti-yellowing agents have their own advantages. The choice of the appropriate type depends on the specific application scenario, cost budget and expected results. In the field of automotive interiors, composite formulas are usually used, combined with different types of anti-yellowing agents to achieve optimal protection.
