<P>PROBLEM TO BE SOLVED: To provide an ethylene-propylene-diene rubber composition having gas-sealing properties, refrigerant resistance, acid resistance, low-temperature resistance, compression set resistance, etc., free from adhesiveness to metallic materials or resin materials and producible without deteriorating intrinsic productivity of the ethylene-propylene-diene rubber. <P>SOLUTION: The ethylene-propylene-diene rubber composition includes (a) a copolymer obtained by copolymerization of ethylene, propylene and an unconjugated diene, (b) an amide compound having a melting point of ≥100°C, (c) an organic peroxide and (d) a polyfunctional unsaturated compound having two or more double bonds. <P>COPYRIGHT: (C)2010,JPO&INPIT |
