UHMWPE has the following advantages: 1. High wear resistance (abrasion than carbon steel, etc.) 2. corrosion resistance (acid, alkali solution from corrosion) 3. low coefficient of friction (friction do pieces can increase wear life, it can also play the energy saving effect) 4. impact resistance (either external shocks or internal forces fluctuations make it difficult to crack, to provide security) 5. aging resistance (stable performance, anti-aging good) 6. Health nontoxic (itself tasteless, non-toxic, odorless, no harm to the human body) product features excellent abrasion resistance, good low temperature impact resistance, self-lubricating, non-toxic, water resistance, chemical resistance, heat resistance than the general PE, disadvantage is that the heat resistance (heat distortion temperature) is low, poor formability, as general plastic outer surface hardness, stiffness, creep resistance, coefficient of expansion is too large. UHMWPE poor mobility, high viscosity molten state, is in the form of a highly viscous rubber-like elastic body, by pressing and sintering only early molding methods, is also available for extrusion, injection molding and blow molding processing methods. Mechanical performance than the usual high-density polyethylene. Has outstanding impact resistance, resistance to stress cracking resistance, high temperature creep resistance, low coefficient of friction, self-lubricating, excellent chemical resistance, fatigue resistance, noise damping resistance, radiation resistance. Use temperature 100 ~ 110 ℃. Cold, and can be used at -269 ℃. Density 0.935g / cm3, molecular weight 2,000,000 product, its tensile strength 40MPa, elongation at break of 350%, flexural modulus of 600MPa, Izod notched impact red constantly. The amount of wear (MPC method) 20mm.
