Abstract:
A conveyor belt obtained by crosslinking a rubber composition for a conveyor belt, said composition comprising(A) 100 parts by weight of an ethylene/alpha-olefin containing 4 to 20 carbon atoms/non-conjugated polyene copolymer rubber, wherein the mole ratio of ethylene/alpha-olefin is from 65/35 to 73/27, and having a diene unit derived from a non-conjugated diene represented by the general formula (1) â€ƒwherein n is an integer of 0 to 10, R1 represents a hydrogen atom or an alkyl group containing 1 to 10 carbon atoms, and R2 represents a hydrogen atom or an alkyl group containing 1 to 5 carbon atoms, or the general formula (2) â€ƒwherein R3 represents a hydrogen atom, or an alkyl group containing 1 to 10 carbon atoms, and wherein said copolymer rubber has an intrinsic viscosity (&eegr;), measured in decalin at 135Â° C., of 2 to 2.7 dl/g, (B) 0.5 to 15 parts by weight of an organic peroxide, (C) 30 to 80 parts by weight of a carbon black, and (D) 5 to 25 parts by weight of a softening agent.
