Unreinforced Polyester Offers Wear-Resistance/Dimensional Stability
ErtalyteÒ TX has wear-resistance and dimensional stability, surpassing other common wear-grade plastics and excellent resistance to many harsh chemicals, including aggressive food products, cleaning solutions and petroleum products. It outlasts unfilled nylons (PA) by a minimum factor of 8 and lasts a minimum of 50 times longer than unfilled acetals (POM). Even industry standard wear materials, such as PTFE-filled acetal and oil-filled nylon, do not offer for its performance. Because of the material's unique composition, its wear resistance increases as bearing velocities increase. It also maintains tight dimensions and close tolerances in wet environments, unsuitable for nylon materials.

The material is used for machined mechanical components, involving both high-pressure and high-velocity conditions. The enhanced-wear material is also well-suited for applications involving soft metal and plastic-mating surfaces, including gears and bearings, which require no startup or running lubrication. It has FDA and USDA compliance and can be used for machined components for food packaging and processing equipment.

Developed and manufactured by Quadrant Engineering Plastic Products, Ertalyte TX is an unreinforced, semi-crystalline thermoplastic polyester (PET-P) with an integral solid lubricant for improved wear and slip-stick resistance. It is available from stock in many rod and sheet sizes. Custom sized rod and sheet as well as tubular shapes are possible.
