As a highly efficient and environmentally friendly catalyst, the post-matured catalyst TAP (Triethylenediamine-based Amine Polyol) has been widely used in high-performance polyurethane foaming systems in recent years. This article will introduce in detail the preparation process, product parameters, performance characteristics and application fields of high-performance polyurethane foaming system based on post-ripening catalyst TAP.

1. Basic principles of polyurethane foaming materials

1.1 Chemical reaction of polyurethane

The preparation of polyurethane mainly involves two chemical reactions: the addition reaction of isocyanate and polyol and the reaction of isocyanate and water. The former generates polyurethane chains, while the latter generates carbon dioxide gas to form a foam structure.

Reaction of isocyanate with polyol:
[
R-NCO + R’-OH rightarrow R-NH-COO-R’
]
This reaction forms polyurethane chains, which are the main structural unit of polyurethane materials.
Reaction of isocyanate with water:
[
R-NCO + H_2O rightarrow R-NH_2 + CO_2
]
This reaction produces carbon dioxide gas, which is the key to the formation of bubbles in polyurethane foaming materials.

1.2 Foaming process

The preparation process of polyurethane foaming materials mainly includes the following steps:

Raw material mixing: Mix raw materials such as polyols, isocyanates, catalysts, foaming agents, etc. in a certain proportion.
