Abstract

This invention relates to the production of low density resole foams from resole resins. The foams have a density of 2.0 pounds per cubic foot (32.037 kg/m3) or less and are produced with a blowing agent consisting of a HCFC or a HFC and a perfluoroalkane, wherein the perfluoroalkane comprises 1 to 5 weight percent of total blowing agent weight, and wherein the HCFC or HFC has a boiling point of below 0°C.
