BELT USING HIGH PERFORMANCE COST-EFFECTIVE ELASTOMERIC MATERIAL

A belt body has an outer surface and an inner facing toothed surface and includes or is comprised of an elastomeric composition; and tensile members. The elastomeric composition including: from about 50 to 90 parts per hundred rubber of a zinc diacrylate modified hydrogenated acrylonitrile-butadiene rubber, and/or an unmodified hydrogenated acrylonitrile-butadiene rubber; from about 10 to 50 parts per hundred rubber of a peroxide curable polyepichlorohydrin copolymer or terpolymer; wherein the elastomeric composition is cured using a free radical promoting material, wherein the free radical promoting material is a peroxide selected from the group consisting of diacyl peroxides, peroxyesters, dialkyl peroxides and peroxyketals and is used in an amount from about 0.5 to 7 parts per hundred rubber, and wherein the peroxide co-agent is selected from the group consisting of 1, 2 polybutadienes, organic acrylates, organic methacrylates, metal salts of an alpha, beta-unsaturates organic acid and mixtures thereof and is used in an amount from about 2 to about 10 parts per hundred rubber.
