1.1 What is PU soft foam amine catalyst?

PU soft foam amine catalyst is a catalyst used in the foaming process of polyurethane (PU) and is mainly used to adjust the rate of foaming reaction and the structure of the foam. It can significantly improve the insulation properties, mechanical strength and durability of PU foam while reducing the impact on the environment.

1.2 Working principle of PU soft foam amine catalyst

PU soft foam amine catalyst promotes the formation of PU foam by accelerating the reaction between isocyanate and polyol. The selection and dosage of catalysts directly affect the density, pore size distribution and mechanical properties of the foam. By precisely controlling the type and amount of catalyst, PU foam materials with excellent thermal insulation properties can be prepared.
