An EPDM composition which contains, as a crosslinking agent, an organic peroxide in an amount of 0.2 to 4.0 parts by weight relative to 100 parts by weight of EPDM having an ethylene content of 50 to 58% by weight and a Mooney viscosity (ML1+4) (at 100 DEG C) of 10 to 48. The EPDM composition shows an excellent blistering resistance under co-presence of flon gas / refrigerating machine oil which is a matter of concern in practical use as a rubbery material for molding a sealing material for a flon-type cooling medium (e.g., R134a), and also shows an excellent molding property. A sealing material produced by vulcanization-molding the EPDM composition, when used for sealing of a flon-type cooling medium, shows a smaller amount of permeation / leak of the cooling medium compared to that in a sealing material comprising hydrogenated NBR which has been used as a shaft seal for a compressor provided in an automotive air-conditioning system.
