Application of delayed amine catalyst C225 in high-performance polyurethane foams

1. Introduction

Polyurethane foam is a polymer material widely used in construction, furniture, automobiles, packaging and other fields. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, in the production process of polyurethane foam, the selection of catalysts has a crucial impact on the performance of the product. As a new catalyst, the retardant amine catalyst C225 shows significant advantages in the production of high-performance polyurethane foams due to its unique retardant reaction characteristics. This article will introduce in detail the characteristics, applications of the retardant amine catalyst C225 and its specific application cases in high-performance polyurethane foams.
