Rubber Composition For Transmission Belt And Transmission Belt

Abstract: The present invention pertains to a rubber composition for a transmission belt, the rubber composition comprising: a polymer component including an ethylene-a-olefin elastomer; carbon black; and clay. The Mooney viscosity of the ethylene-a-olefin elastomer at 125°C is 25 ML(1+4) @ 125°C or less, and the pH of the clay is 5.5 or higher. The total amount of the carbon black and the clay is 80-180 parts by mass per 100 parts by mass of the polymer component, and the mass ratio of the clay to the carbon black is clay/carbon black = 0.2/1 to 1.2/1.
