摘要

An object of the present invention is to provide an ethylene-acrylic rubber composition that is excellent in the compression set and also in the crosslinking bonding even when no secondary crosslinking is caused therein, an ethylene-acrylic rubber produced by causing primary crosslinking in the composition, a rubber metal composite formed by bonding the ethylene-acrylic rubber and a metal with each other, and a bonded piston sealing including the rubber metal composite. The object is achieved by an ethylene-acrylic rubber composition including 1 to 7 phr by weight of calcium hydroxide relative to 100 phr by weight of a binary ethylene-acrylic rubber polymer that includes ethylene and an acrylic acid ester, an ethylene-acrylic rubber produced by causing peroxide-crosslinking by primary crosslinking in the ethylene-acrylic rubber composition, a rubber metal composite formed by crosslinking-bonding the ethylene-acrylic rubber and a metal with each other bonded with the primary crosslinking, and a bonded piston sealing including the rubber metal composite.
