PROCESS FOR THE MANUFACTURE OF POLYURETHANE FOAMS

摘要

PROCESS FOR THE MANUFACTURE OF POLYURETHANE FOAMS A novel process for the manufacture of polyurethane foams by reacting a reaction mixture comprising a) a polyisocyanate component, with b) a polyol component containing no salt groups; in the presence of c) at least one blowing agent, d) catalysts. The catalyst comprise at least one carboxylic acid salt containing ether groups and no ester groups. The reaction mixture may optionally contain e) further auxiliary substances and additives. This invention also relates to back-foaming of a plastics sheet as skin for the purpose of manufacturing composite bodies, and the composite bodies thus manufactured.
