Oil-resistant rubber composition |
摘要 |
An oil-resistant rubber composition comprising (A) 90 to 10 parts by weight of an unsaturated nitrile-conjugated diene rubber having a DELTA Tg of 58 DEG C. or more and an average bound nitrile content of 15 to 50% by weight, (B) 10 to 90 parts by weight of at least one rubber selected from the group consisting of an ethylene-propylene type copolymer rubber, a natural rubber and a polyisoprene and (C) 0 to 50 parts by weight, per 100 parts by weight of the total of (A) and (B), of at least one component (C) selected from the group consisting of a styrene polymer and a polyalkenamer. Said rubber composition is oil-resistant and excellent in mechanical properties such as tear strength, resistance to crack growth, etc.
