Method for post-ripening catalyst TAP to improve durability of polyurethane products

Introduction

Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, etc. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, polyurethane products often face durability problems during use, such as aging, cracking, discoloration, etc. In order to improve the durability of polyurethane products, the post-ripening catalyst TAP (Triazine-based Amine Polyol) was introduced into the production process of polyurethane. This article will introduce in detail the mechanism of action, usage method, product parameters and its effect on improving the durability of polyurethane products.

1.2 Mechanism of action of TAP catalyst

TAP catalysts enhance the crosslinking density of the product by promoting the crosslinking reaction of the polyurethane molecular chain, thereby enhancing its mechanical strength, heat resistance and chemical resistance. Specifically, during the post-ripening process of polyurethane, the TAP catalyst can accelerate the reaction between isocyanate and polyol, forming a more stable three-dimensional network structure.

2. How to use TAP catalyst
