UHMWPE sheets and parts are made from a material with a minimum molecular weight of 5.0 million. This material has a density of 0.93-0.95 g/cm3, water absorption of less than 0.01%, tensile strength of at least 18N/mm2, and elongation of at least 50%. It also has high impact strength, hardness, compressive strength, and thermal conductivity, with low volume and surface resistivity. This material is suitable for use in temperatures from -80 to 80 degrees Celsius and has low coefficients of friction, negligible moisture/solvent absorption, and excellent weather resistance.
