PUR/PIR rigid foams based on aliphatic polyester polyols

摘要

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