초록

Rigid foams having improved insulation properties are made by reacting a polyisocyanate with an isocyanate-reactive material in the presence of a blowing agent mixture composed of from about 1 to about 30% by weight of at least one C.sub.2 -C.sub.5 polyfluoroalkane and from about 70 to about 99% by weight of an HCFC, preferably an HCFC selected from chlorodifluoromethane, 1,1-dichloro-1-fluoroethane, 1-chloro-1,1-difluoroethane and mixtures thereof.
