Abstract
An endless power transmission belt having (1) a tension section; (2) a cushion section; and (3) a load-carrying section disposed between the tension section and cushion section; and the belt containing a free radically-cured elastomeric composition comprising the reaction product of (a) an ethylene-alpha-olefin elastomer; (b) from 10 to 100 parts by weight per 100 parts by weight of total rubber (phr) of a non-migratory internal lubricant selected from the group consisting of graphite, molybdenum disulfide, polytetrafluoroethylene and mixtures thereof; and (c) from 0.1 to 100 phr of curative coagent selected from the group consisting of organic acrylates, organic methacrylates, metal salts of an alpha-beta saturated organic acid and mixtures thereof.
