UHMW

UHMW ~ Polyethylenes

Polyethylenes are semi-crystalline materials with excellent chemical resistance, good fatigue and wear resistance, and a wide range of properties. Polyethylenes provide good resistance to organic solvents, degreasing agents and electrolytic attack. They have a higher impact strength, but lower working temperatures and tensile strengths than polypropylene. They are light in weight, resistant to staining, and have low moisture absorption rates. High Density Polyethylene (HDPE) HDPE offers excellent impact resistance, light weight, low moisture absorption, and high tensile strength. HDPE is also non-toxic and non-staining and meets FDA and USDA certification for food processing.

Ultra High Molecular Weight Polyethylene (UHMW PE) Light weight, high in tensile strength and has excellent machinability. UHMW PE is the ideal material for many wear parts in machinery and equipment. UHMW PE is self-lubricating, shatter resistant, long-wearing, abrasion and corrosion resistant. It meets FDA and USDA acceptance for food and pharmaceutical equipment.  Limitations good performer in applications up to 180 °F (82 °C) or when periodically cleaned with live steam or boiling water to sterilize.
