The English name of ultra-high molecular weight polyethylene (UHMWPE) is a polyethylene with a molecular weight of more than 1 million. The mechanical properties are higher than that of ordinary high-density polyethylene. It has outstanding impact resistance, stress crack resistance, high temperature resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance, etc. Use temperature 100 ~ 110 ℃. Good cold resistance, can be used at -269 ℃. The product with a density of 0.985g/cm3 and a molecular weight of 2 million has a tensile strength at break of 40MPa, an elongation at break of 350%, and a flexural modulus of elasticity of 600MPa. Abrasion amount (MPC method) 20mm.

UHMWPE has excellent performance, good low temperature impact resistance, self-lubrication, non-toxic, water resistance, chemical resistance, heat resistance is better than general PE, the disadvantage is low heat resistance (heat deformation temperature), processing and molding Poor performance, outer surface hardness, rigidity, expansion coefficient is too large.
