摘要

PPROBLEM TO BE SOLVED: To provide a new rubber composition having excellent resistance to DME. PSOLUTION: The rubber composition comprises a rubber component and a swelling control lubricant that controls swelling of the rubber component by DME and provides the rubber component with lubricity. The swelling control lubricant contains at least any one of polyethylene powder, silicone powder and polytetrafluoroethylene powder. The rubber component is at least any one of a hydrogenated nitrile rubber (HNBR), a nitrile rubber (NBR) and an ethylene-propylene-diene rubber (EPDM). PCOPYRIGHT: (C)2010,JPO&INPIT
