Abstract:
An endless power transmission belt having(1) a tension section; (2) a cushion section; and (3) a load-carrying section disposed between said tension section and cushion section; and the belt containing an elastomeric composition consisting essentially of (a) 100 parts of a rubber derived from (i) 50 to 100 parts by weight of an ethylene alpha olefin elastomer; and (ii) 0 to 50 parts by weight of a rubber selected from the group consisting of silicone rubber, polychloroprene, epichlorohydrin, acrylonitrile rubber, hydrogenated acrylonitrile rubber, zinc salts of unsaturated carboxylic acid ester grafted hydrogenated nitrile butadiene elastomer, natural rubber, styrene-butadiene rubber, 1,4-trans-polybutadiene, ethylene-vinyl-acetate copolymer, ethylene methacrylate copolymers and terpolymers, chlorinated polyethylene, chlorosulfonated polyethylene, alkylated chlorosulfonated polyethylene trans-polyoctenamer, polyacrylic rubber, and mixtures thereof; (b) from 1 to 30 parts by weight per 100 parts by weight of total rubber (phr) of a polybutadiene adduct of maleic acid anhydride.
