IMPROVED INSULATION PERFORMANCE FOAMS

Abstract:

The present application provides foams having improved insulation and thermal performance and processes of forming said foams. Exemplary foams described herein are prepared according to a process comprising reacting or extruding a foamable composition comprising (i) a compound selected from E-CHCl.dbd.CHCF.sub.3, Z--CF.sub.3CH.dbd.CHCF.sub.3, and E-CF.sub.3CH.dbd.CHCF.sub.3, or any mixture thereof, and (2) a C.sub.5 hydrocarbon (e.g. cyclopentane), under conditions effective to form the foam.
