A Summary Report of UHMWPE Wear Resistant Materials

Ultra-High Molecular Weight Polyethylene (abbreviated as UHMWPE) is a linear engineering thermoplastic engineering plastic with excellent overall performance. It‘’s molecular structure is the same as that of normal polyethylene, and it is in the molecular main chain. Chains with (-CH2-CH2-) are attached and have an extremely large molecular weight of 106 or more. It is widely used in general machinery, agricultural machinery, textile machinery, automobile, mining, papermaking, chemical, food industry due to its unique properties such as excellent abrasion resistance, self-lubrication and impact resistance compared to other engineering materials. Such as non-stick, wear-resistant, low noise and self-lubricating parts and other fields. In addition, it can also be used as a special film, large container, large special-shaped pipe and plate, etc. It is used for the lining of cargo chutes, hoppers, and warehouses.

Ultra-high-molecular-weight polyethylene generally refers to polyethylene with a relative molecular mass of 1 million or more, and the relative molecular mass of ultra-high-molecular-weight polyethylene produced in Germany is already as high as 10 million or more. It has the following advantages: 

(1) Excellent wear resistance, Mortar wear test shows that it is several times more resistant than metals such as carbon steel and copper, and four times more resistant than nylon; (2) High impact strength compared to PA6 10 times larger than PP; (3) Absorb shock shock and prevent noise; (4) Friction coefficient is very low, far smaller than nylon and other plastics, and can be lubricated; (5) It is not easy to adhere to foreign matter, and it is excellent when sliding. The anti-adhesive properties; (6) chemical resistance, the disease can shield atomic radiation; (7) operating temperature range from - 265 °C to +100 °C, low temperature to -195 °C, can still maintain good toughness and strength , Will not be brittle; (8) Non-toxic, non-polluting, recyclable recycling, compared with other plastics have good thermal stability and non-absorbent, can maintain dimensional accuracy without deformation; (9) low cost. Therefore, UHMW polyethylene is the best overall engineering plastic in engineering plastics. It has almost concentrated the advantages of various plastics. In fact, there is no single polymer material with so many excellent properties. However, it also has shortcomings, mainly due to poor temperature resistance, low hardness, low tensile strength, and poor flame retardancy.
