A PUR/PIR (sic) rigid foam is a reaction product of an organic polyisocyanate component with an isocyanate reactive component comprising aliphatic polyester polyol(s) that contains units derived from adipic acid and one of glutaric, succinic and sebacic acid at an index of 100-400. An independent claim is also included for a process of producing PUR/PIR rigid foams, comprising spraying a reaction mixture comprising an organic polyisocyanate component and an isocyanate reactive component comprising aliphatic polyester polyol(s) that contains units derived from adipic acid and one of glutaric acid, succinic acid and sebacic acid at an index of 100-400. |
