ABSTRACT:
Rubber compositions are provided comprising per 100 parts by weight from about 65 to about 97 parts by weight of at least one rubber selected from the group consisting of natural rubber, synthetic cis-1,4-isoprene rubber, cis-1,4-butadiene rubber and brominated butyl rubber, and from about 3 to about 35 parts by weight of at least one carboxylated rubber selected from the group consisting of carboxylated styrene-butadiene rubber, carboxylated butadiene rubber, carboxylated isoprene rubber and carboxylated natural rubber, from about 20 to about 60 parts by weight per 100 parts by weight of rubbers of carbon black, from about 3 to about 25 phr of process oil and from about 1 to about 10 parts by weight per 100 parts by weight of rubber of metal oxide. The compositions are vulcanizable and the vulcanizates exhibit a good combination of vibration damping and noise insulating properties and are suitable for automotive engine mounts.
