ABSTRACT:
A vulcanizable ethylene-propylene rubber composition with improved thermal aging resistance is made from ethylene-propylene rubber, an alkoxysilane such as N-(N-vinylbenzylaminoethyl)-gamma-aminopropyltrimethoxysilane or its hydrochloride, a reinforcing filler, and a vulcanizing agent. These vulcanizable ethylene-propylene rubber compositions can also contain vinyl group-containing organopolysiloxane gum. These compositions cure to rubber with excellent mechanical properties, excellent electrical insulation properties, and thermal aging resistance which makes them suitable for electrical wire insulation.
