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 UHMWPE rods Which cheap, excellent chemical resistance, fatigue resistance, noise damping, anti-nuclear 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 350% ultra high molecular weight polyethylene rod diameter, the flexural modulus of 600MPa, Izod notched impact red constantly. The amount of wear (MPC method) 20mm. Since the viscosity of the high molecular weight polyethylene (UHMW-PE) in a molten state up to 108Pa * s quality ultra high molecular weight polyethylene rod, poor flowability, melt index is almost zero, it is difficult by conventional machining methods processing. Ultra-high molecular weight polyethylene (UHMW-PE) processing technology has been developing rapidly, through the transformation of ordinary processing equipment, has led to the ultra-high molecular weight polyethylene (UHMW-PE) from the initial pressing - sintering development of extrusion, injection molding and blow molding and other special method.
