abrasion resistant UHMWPE liner for bunker

UHMWPE sheet has an incredible resistance to abrasion. It will outperform almost any engineering plastic for abrasion resistance and is probably one of the best materials for lining chutes and hoppers for products such as sand, aggregate and concrete or any other highly abrasive moving product.

Another important property is it's incredibly low co-efficient of friction. It is one of the lowest of all engineering plastics and will produce components with a very high life span with very low drag, which means very little will stick to it. Its also resistant to many dilute acids, solvents and cleaning agents.

UHMWPE has a maximum continuous operating temperature of plus 90°C and a short term operating temperature of plus 120°C. Its a very tough material, with the highest impact strength of any thermoplastic presently made.

Abrasion resistant Panel liner Advantages

Extremely high wear resistance:

it is very valuable in engineering application, the ratio of carbon steel, stainless steel, bronze new wear-resisting of even higher.

High shock resistance:

Extremely low coefficient of friction: ultra-high molecular weight polyethylene is very wear-resisting, and low friction coefficient, good self-lubrication, is an ideal bearing bushings, slider, lining material. The use of ultra-high molecular weight polyethylene as friction parts of equipment, besides can improve the wear life, energy saving effect can be received.

Low temperature resistance:

because of ultra-high molecular weight polyethylene is an excellent material toughness, and its low resistance is also very good, in - 269 °C, low temperature, still have certain ductility, and shows no sign of embrittlement.
