Abstract
A rubber composition includes hydrogenated acrylonitrile-butadiene rubber (HNBR), a copper dithiocarbamate salt compound and sulfur. The use of the copper dithiocarbamate salt compound results in the vulcanized rubber composition exhibiting improved heat resistance as compared to a rubber material that does not include the copper dithiocarbamate salt compound. Toothed belts and V-ribbed belts can be made using the rubber composition to produce belts exhibiting improved heat resistance.
