Abstract (en)
[origin: WO2010006831A1] The invention relates to a drive belt (1), particularly a toothed belt, having an elastic base body, comprising a cover layer (2) as the belt back, and a subframe (4) having a power transmission zone (7), wherein the base body is made from oil-resistant vulcanized rubber on the basis of a copolymer comprising butadiene and acrylonitrile, particularly HNBR, wherein according to the invention the proportion of acrylonitrile (CAN proportion) is <33 % by weight with regard to the total weight of the copolymer. The particularly advantageous CAN proportion is 20 to 35 % by weight. The power transmission zone (7) is typically also equipped with a textile cover (8), which is further provided with an oil-resistant protective layer (9), which is preferably made from PTFE.
