Abstract: The present invention relates to elastomer toothed belts comprising a fabric spanning the teeth of the toothed belt, wherein the elastomer mixture forming the teeth contains a crosslinked ethylene-propylene rubber (EPM) and/or a crosslinked ethylene-propylene terpolymer rubber (EPDM) accounting for at least 70% by weight of the elastomer mixture based on the polymer proportion and wherein an interlayer is arranged between the fabric and the elastomer mixture forming the teeth which contains at least 70% by weight of hydrogenated acrylonitrile-butadiene rubber (HNBR) based on the polymer proportion of the interlayer. Such elastomer toothed belts are halogen-free and feature improved durability and good low-temperature stability properties. The present invention further relates to processes for producing such elastomer toothed belts and to the use of a layer of hydrogenated acrylonitrile-butadiene rubber (HNBR) in such toothed belts to increase service life, to improve low-temperature stability and to improve the adhesion between the teeth and the fabric.

Abstract: A V-ribbed belt having an elastic main body constructed from at least one rubber mixture including an outer ply as a belt backing and a substructure having a ribbed force-transmitting side. To improve friction and optimize service life the V-ribbed belt has a coating made of a knitted fabric on its force-transmitting side, in which the average basis weight of the textile before vulcanization is between 140 and 190 g/m2.
