Ultra high molecular weight polyethylene sheet properties

Ultra high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering material that combines all the advantages of plastics. With wear resistance, impact resistance, chemical corrosion resistance, their own lubrication, low temperature wear resistance coefficient is small, light weight, energy absorption, aging resistance, flame retardant, antistatic and other excellent performance, the use of UHMW-PE plate lining power plant, coal plant, coking plant coal bunker; Ore and other material silos of cement plant, steel plant and aluminum plant; Grain, feed, pharmaceutical industry granary, wharf hopper, etc., can prevent sticky material, speed up the feeding speed, eliminate douce accident, save the investment and cost of air gun, lining bulk hold can avoid powder adhesion to the hold and reduce the damage of loading and unloading machinery to the bulkhead. With the development of plastic processing technology, the application field of UHMW-PE will be broader.

A, high wear resistance, due to its unique molecular structure, wear resistance is higher than the general metal plastic products, 6.6 times of carbon steel, 5.5 times of stainless steel, 27.3 times of brass, 6 times of nylon, 5 times of ptfe;

B, good self-lubrication performance, small friction coefficient, small flow resistance, energy saving;

C, high impact strength, good toughness, even at low temperature, by strong impact will not fracture;

D, excellent chemical corrosion resistance, resistance (except concentrated sulfuric acid, concentrated nitric acid, a few organic capacity agent) almost all acid, alkali, salt medium;

E, non-toxic, tasteless, no exudate;

F, good electrical properties, very low water absorption;

G, excellent resistance to environmental stress cracking, 200 times that of ordinary polyethylene;

H, excellent low temperature resistance, not brittle even at -180C °.
