Abstract
A rubber composition obtained by subjecting a mixture of (I) 35-95 parts by weight of a fluoroelastomer and (II) 65-5 parts by weight of an ethylene-.alpha.-olefin copolymer rubber in which the total of the (I) component and the (II) component is 100 parts by weight and a crosslinking agent for the ethylene-.alpha.-olefin copolymer rubber (II) to reaction while imparting shearing deformation to the mixture. Said rubber composition is excellent in processability on roll and in extruder, heat resistance, steam resistance, weather resistance, compression set and resistance to compressive load. A rubber article is obtained by subjecting the above rubber composition and a crosslinking agent for the fluoroelastomer (I) and optionally at least one additive to reaction, said rubber article being excellent in heat resistance, weather resistance, compression set and resistance to compressive load and hence can be used in the fields of general industry, electric industry and chemical industry.
