UHMW-PE

Extremely tough abrasion resistant, low cost plastic, used for a wide range of wear applications

UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance. The versatility of polyethylene has made it a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance.

UHMW MATERIAL OPTIONS

UHMW Liners – UHMW sheet is often used for lining chutes and hoppers to protect metal surfaces and to keep solid materials like sand, wood chips, or coal moving smoothly.

UHMW Parts – Easy to fabricate, UHMW is also used for packaging, conveyor, and food processing machinery parts including star wheels, idler sprockets, and under-chain wear strips.

UHMW Wood Replacement – UHMW offers very low moisture absorption and is a popular choice for marine construction applications like dock fender pads, pile guards, and anti-skid walkways. UHMW does not corrode, rot, or splinter like wood.

UHMW Grades – Several grades of UHMW are available, including reprocessed, enhanced bearing and wear, and FDA compliant. 

Tech Tip – Ultra high molecular weight polyethylene has a relatively high coefficient of thermal expansion. This may make it difficult to hold tight tolerances on UHMW parts that will be exposed to changing temperatures.
