Method of producing rigid foams and products produced therefrom

摘要

A thermosetting plastic foam solid formed from the reaction product of: (a) either polyisocyanate or isocyanate; (b) a polyol; (c) a catalyst which is capable of promoting the thermosetting reaction between the polyisocyanate or isocyanate and the polyol; and (d) a blowing agent comprised at least partially from a high purity cyclopentane product, wherein the high purity cyclopentane product is about 95% or greater pure cyclopentane, and, optionally, (e) water and/or (f) liquid flame retardant.
