THERMALLY DEFORMABLE HARD FOAM AND ITS PRODUCTION AND USE

摘要

Thermoformable rigid foams are made by reacting an organic polyisocyanate with a polyol component. The polyol component includes at least one organic polyhydroxyl compound having a hydroxyl number of from 28 to 1200, a foaming agent, a catalyst and a compound which masks isocyanate groups. Preferred isocyanate masking compounds are epsilon -caprolactam and nonyl phenol. The foam thus obtained may then be molded and crosslinked by heating it to a temperature of from 150 DEG to 190 DEG C. These foams are particularly useful as interior trim for motor vehicles.
