Abstract
Hydrogenated nitrile rubber based vulcanizates which have at least one of improved load bearing capabilities, improved abrasion resistance and reduced heat build-up are provided, the vulcanizates having been produced by vulcanization of a compound consisting essentially of 100 parts by weight of hydrogenated nitrile rubber, 10 to 85 parts by weight of zinc diacrylate and 1 to 10 parts by weight of an organic peroxide. Such vulcanizates are useful in belts, rolls and hoses.
