Abstract
A belt having a body, a tensile member and an outer surface. The body comprises an elastomer. An outer surface of the belt having a profile, foe example teeth. A layer of Ultra high molecular weight polyethylene thermoplastic (UHMWPE) is bonded to the profile surface. The layer bonded to the profile surface having a low softening point allowing it to conform to a mold shape prior to cure of the rubber body material. The layer having a molecular weight in the range of 3-7 million grams per mole. The layer causes the belt to exhibit superior abrasion resistance and flexibility while reducing the cost per belt as compared to fabric jacket belts. The UHMWPE jacket belt has significantly reduced dust and debris production during operation.
