Description
UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance. The versatility of the polyethylene has made it a popular plastic for countless indrustrial applications that require durability, low friction, and chemical resistance. Applications include UHMW wear strips, chain guides, pacakaging machinery parts, and marine dock fender pads. Known for an extremely high molecular weight, UHMW features an unsurpassed combination of slickness, toughness and chemical resistance. UHMW's molecular weight ranges from 3.1 million to 100 million grams per mole, with an abrasion resistance that continues to improve as molecular weight increases. UHMW is easy to machine with common woodworking tools, making it extremely cost effective, and outperforms metal in many applications. UHMW sheets are used often in food and marine industries due to their resistance to bacteria and moisture. Additionally, UHMW often replaces wood in outdoor applications, since UHMW is not affected by different kinds of weather and does not rot.
