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

摘要

Provided is a heat-resistant rubber composition for heat-resistant conveyor belts. The rubber composition for heat-resistant conveyor belts comprises an ethylene-1-butene copolymer having a mooney viscosity at 125°C of not less than 20; and an ethylene-propylene copolymer having a mooney viscosity at 125°C of not less than 20 and having an ethylene content of 40 to 60% by mass. The mass ratio of the ethylene-1-butene copolymer to the ethylene-propylene copolymer is 10/90 to 90/10.
