Abstract:
A rubber composition comprising (A) a rubber ingredient comprised of (a) a nitrile group-containing highly saturated copolymer rubber having an iodine value of not larger than 120 and (b) an acrylic ester polymer rubber containing at least 80% by mole of at least one kind of monomer units selected from alkyl acrylates and alkoxyalkyl acrylate, and which is free from a carbon-carbon unsaturated bond except for the carbon-carbon double bonds of a benzene ring, at an (a)/(b) ratio of 40/60 to 90/10 by weight, and (B) an ethylene-1-octene copolymer, the (A)/(B) ratio being in the range of 30/70 to 70/30 by weight; said rubber composition further comprising an organic peroxide and being free from an auxiliary capable of covulcanizing the rubber ingredient (a) and the rubber ingredient (b) with the organic peroxide.
