Acrylic Rubber Composition And Acrylic Rubber Vulcanizate

摘要

It is to provide an acrylic rubber composition which provides an acrylic rubber vulcanizate retaining high tensile strength and modulus even if a long-term thermal load is applied and contains no component limited by environmental regulations. The above object is attained by an acrylic rubber composition comprising 100 parts by weight of a carboxyl group-containing acrylic rubber and 0.3 to 8 parts by weight of a styrenated diphenylamine compound, and by an acrylic rubber composition further comprising 0.05 to 20 parts by weight of a crosslinking agent besides the above components.
