RUBBER COMPOSITION FOR HEAT-RESISTANT CONVEYOR BELTS AND HEAT-RESISTANT CONVEYOR BELT

摘要

A rubber composition for a heat-resistant conveyor belt excellent in heat resistance is provided. Wherein the rubber composition for a heat-resistant conveyor belt comprises an ethylene / 1-butene copolymer having a Mooney viscosity of at least 20 at 125 DEG C and an ethylene / propylene copolymer having a Mooney viscosity at 125 DEG C of 20 or more and an ethylene content of 40 to 60% And the mass ratio of the ethylene / 1-butene copolymer to the ethylene / propylene copolymer is 10/90 to 90/10.
