MOLDING COMPOSITION Russian patent published in 1999 - IPC

Abstract SU 1055143 A1

FIELD: epoxide compositions. SUBSTANCE: molding composition including epoxy-4,4Т-isopropylidene-diphenol resin (100 wt parts), pyromellitic acid dianhydride (15-20 parts), and glass-fiber filler (200-230 parts) is distinguished by being supplemented with dihydroxydiphenylsulfone dihydroxydiethyl ether (5-8 parts) and calcium stearate (7-9 parts). EFFECT: increased durability of composition, reduced specific pressure in molding procedure, and increased heat resistance of products.
