ABSTRACT:
A thermosetting plastic foam solid is obtained using a blowing agent comprised at least partially from depolymerization of dicyclopentadiene into essentially pure cyclopentane. This unique hydrocarbon is miscible in polyester polyols, where others, such as extracted cyclopentane, are not. In a blend of 15 parts of liquid flame retardant per hundred parts polyester polyol, the mixture is both stable and has a suitably low viscosity.
