Reprocessed UHMW (Ultra High Molecular Weight Polyethylene) is a machinable thermoplastic that serves as an economical and environmentally friendly option for non-food applications. Like virgin UHMW, reprocessed UHMW is a highly durable, cost-efficient, and versatile material with superior impact and chemical resistance. Its durability, extremely low coefficient of friction, and inherent lubricity make UHMW ideal for applications where high levels of friction are likely to arise.

Reprocessed UHMW is made with a blend of virgin and recycled UHMW. Its FDA and USDA compliance and easy machinability make it an extremely versatile, eco-friendly, and cost-effective material for countless non-food applications. Reprocessed UHMW is used extensively in conveying, material handling, and packaging applications where durability and wear resistance are necessary.

Piedmont Plastics works with many suppliers to offer a wide range of plastic materials that will meet any need. Reprocessed UHMW is available in sheets, rods, and tubes in a wide range of sizes and thicknesses. Let the experts at Piedmont help you find the perfect product for your unique application!
