1. Basic concepts of delayed amine hard bubble catalyst
1.1 What is a delayed amine hard bubble catalyst?
The delayed amine hard bubble catalyst is a chemical additive used in the production of polyurethane foam. By delaying the reaction time, the foam material can better control the foaming speed and curing time during the molding process, thereby improving the uniformity and stability of the material.
1.2 Working principle of delayed amine hard bubble catalyst
The delayed amine hard bubble catalyst increases the foaming time of foam by adjusting the amine group activity in the polyurethane reaction so that the reaction maintains a low rate for a specific time. This delay effect allows the foam material to better fill the mold during the molding process, reduce the generation of bubbles and voids, and improve the density and strength of the material.
