A Brief Analysis of Catalysts for Polyurethane Raw Materials

during the preparation of polyurethane foam, the role of catalyst is mainly to adjust the speed of foaming reaction and gel reaction to keep them in good balance. 1、 amine catalysts triethylenediamine is the most important tertiary amine catalyst in soft foam production, with 60% efficacy in promoting the reaction between isocyanates and water, i.e. foaming reaction. the 40% effect is used to promote the reaction…
