UHMWPE Sheet wear resistance is higher than steel, carbon steel wear it eight times, thus greatly extending the life of its use, along with its mechanical properties than the usual high-density polyethylene. UHMWPE sheet has a very good impact resistance, resistance to stress cracking, high temperature creep resistance, low coefficient of friction, self-lubricating, has a very good chemical resistance, fatigue resistance, noise damping resistance, radiation resistance.
Use temperature 100 ~ 110 ℃. Cold, and can be used in the next -269 ℃. Density 0.985g / cm3, the molecular weight of 2 million of goods, its cracking tensile strength 40MPa, elongation of 350% crack, tortuous elastic modulus 600MPa, Izod notched impact punch continued. The amount of wear (MPC method) 20mm.
UHMWPE Sheet has excellent abrasion resistance, excellent low temperature impact resistance, self-lubricating, non-toxic, water resistance, chemical resistance, heat resistance than normally PE, defective heat resistance (heat distortion temperature) low , moldability is poor, the outside appearance of the hardness, stiffness, creep resistance is generally inferior to plastic expansion coefficient is too large. UHMWPE Sheet poor mobility, very high viscosity in the molten state, is in the form of a highly viscous rubber-like elastic body, pre-sintering methods can only be used to limit the molding, this can also be extrusion, injection molding and blow molding process side.
