ANULON-94 Ultra High Molecular-weight Polyethylene (UHMWPE)

Back

ANULON-94 Ultra High Molecular-weight Polyethylene (UHMWPE) has polymer chains 10 to 20 times longer than High Density Polyetylene. The longer Chains (higher molecular weight) give major advantages in toughness, abrasion resistance and freedom from stress cracking. ANULON-94 shares the lubricity, chemical resistance and excellent electrical properties of conventional HDPE. It has several extra-ordinary properties, particularly abrasion resistance (ten times better than carbon steel) and suitable for extremely low temperature applications (-250°C to 90°C); even colder than liquid nitrogen. In the food processing industry, its self lubricion properties and resistance to boiling water are exploited. It complies with FDA requirements for handling food, water and pharmaceuticals. Many uses are based on its noise and shock absorbing properties. In mining industry, ANULON-94 is used as liners in chutes and hoppers due to its excellent abrasion and chemical resistance.

Salient Features of ANULON-94

High notched bar impact toughness and is therefore largely unaffected by impact strength

Excellent sound dampening properties - ideal for controlling environmental and noise pollution

Abrasion and wear resistant and has excellent sliding qualities

Free from corrosion and resistant to most forms of chemical attack

Meets F.D.A. the requirements for handling food stuffs

Light in weight and easy to handle, reduce supporting structural cost

Easily machined on metal and wood working machines and equipments

Wide temperature range capability from -250°C to 90°C

Simplifies maintenance, prolongs life of plant
