Abstract
Foam precursor materials are taught comprising an epoxy resin having an epoxy equivalents value of about 300-4000, a curing agent and a foaming agent. The foam precursor materials may be expanded and cured by heat to form foam materials that exhibit excellent rigidity. The resulting foam materials may have a compression strength of about 200-2000 Kgf and a density of about 0.20 to 0.40 grams per cubic centimeter.
