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.

Thermoplastic jacket belt

A flexible boot of the polymeric type for use with a universal joint where the boot has a radially outermost generally tubular wall section that interconnects to the boot body by oppositely facing peaks and valleys. The thickness of the boot sidewall is controlled to effect desire bending where, in one embodiment, peaks and valleys are thicker than an adjoining sidewall of a corrugation.

Flexible boot for universal joint

A diaphragm for pumps or the like of a dish-shaped body of nonreinforced thermoplastic elastomer having a curvilinear flexure sidewall portion of substantially less thickness than the central and flange portions to which it connects.
