PUR/PIR RIGID FOAMS BASED ON ALIPHATIC POLYESTER POLYOLS

摘要

PUR/PIR rigid foams based on aliphatic polyester polyols are produced b y reacting an organic polyisocyanate with an isocyanate reactive component tha t includes a polyester polyol containing units derived from (1) adipic acid an d (2) at least one of glutaric, succinic and sebacic acid. These foams may be produce d spraying. These foams are particularly suitable for use in laminates.
