Elastomer composition based on EPDM, and a powder transmission belt made essentially out of said elastomer

摘要

An elastomer composition for curing by organic peroxides, the composition comprising an EPDM, a filler such as carbon black, and an additive such as zinc methacrylate, together with an elastomer grafted with maleic anhydride that reacts with the zinc methacrylate to reinforce the curing of the elastomer. The invention applies in particular to the manufacture of power transmission belts.
