Manufacturing foams for making supported foam, by reacting polyol(s) with isocyanate(s) in presence of catalyst, polyepoxide, blowing agent other than chlorofluorocarbon and/or flammable blowing agent

摘要

Manufacturing foams comprises reacting polyol(s) with isocyanate(s) in the presence of catalyst, polyepoxide, blowing agent other than chlorofluorocarbon, and/or flammable blowing agent. The foams comprise (modified) polyurethane. The blowing agent other than chlorofluorocarbon is preferably hydro fluorocarbon.
