Abstract

PURPOSE: To provide title compsn. having excellent heat resistance and suitable for electrical insulating materials, obtd. by blending a compsn. consisting of ethylene- propylene copolymer, two kinds of additives and inorg. mineral with an peroxide, and vulcanizing the resulting blend.
CONSTITUTION: (A) 100pts.wt. of ethylene-propylene copolymer or ethylene-propylene-non-conjugated diene terpolymer is blended with (B) from 6 to 12pts.wt. of at least one benzimidazole selected from 2-mercaptobenzimidazole (zinc salt) and 2-mercaptomethylbenzimidazole as an additive, (C) from 0 to 5pts.wt. of 2,2,4- trimethyl-1,2-dihydroquinoline polymer as an additive and (D) from 50 to 250 pts.wt. of an inorg. mineral such as talc, clay and/or (E) from 20 to 100pts.wt. of carbon black to obtain a compsn. From 2 to 6pts.wt. of org. peroxide crosslinker is blended with the compsn. The resulting blend is valcanized to produce title compsn.
