Retardation of amine catalyst A300: Strategies to reduce defects in polyurethane products

Introduction

Polyurethane (PU) is a multifunctional material widely used in the fields of construction, automobile, furniture, footwear, etc. However, various defects are often encountered in the production process of polyurethane products, such as bubbles, shrinkage holes, uneven surfaces, etc. These defects not only affect the appearance of the product, but may also reduce its mechanical properties and durability. To solve these problems, the delayed amine catalyst A300 came into being. This article will introduce in detail the characteristics, applications of the delayed amine catalyst A300 and its strategies in reducing defects in polyurethane products.

1. Overview of Retarded Amine Catalyst A300

1.1 What is retarded amine catalyst A300?

The retardant amine catalyst A300 is a catalyst specially designed for polyurethane reactions. It allows the polyurethane material to flow and fill the mold better during the molding process, thereby reducing defects in the product.

Bubble is one of the common defects in polyurethane products. The main causes include:

Overfast reaction: The reaction speed is too fast, resulting in the gas being unable to be discharged in time.
Unreasonable mold design: The mold exhaust is poor or the unreasonable design leads to gas retention.
Materials have high moisture content: The moisture in the material produces gas during the reaction.

2.2 Shrink hole

Shrinking holes usually appear in thick-walled parts of the product, and the main causes include:

Ununiform reaction: Uneven temperature distribution during the reaction leads to local shrinkage.
Poor material fluidity: Inadequate material fluidity leads to inability to fill the mold sufficiently.

2.3 Uneven surface

The uneven surface may be caused by the following reasons:

Mold Surface Rough: The surface roughness of the mold affects the surface quality of the product.
Reaction speed is too fast: The reaction speed is too fast, so that the material cannot be evenly distributed.
