Features ultra-high molecular weight polyethylene plate: electrical properties. Volume resistance, breakdown voltage up to 50KV / mm block of coal shearer board processing, a dielectric constant of 2.3. In a wide temperature and frequency range suitable for use as a structural material in electrical engineering. Health non-toxic. UHMW-PE tasteless, non-toxic, odorless block of coal shearer board prices, itself non-corrosive, with physical inertia and physiological adaptation. Historical Development of ultrahigh molecular weight polyethylene plate: UHMW-PE wealth is a source, affordable, excellent performance of a thermoplastic plastic, impact resistance, corrosion resistance, wear resistance, self-lubricating, non-toxicity and a very good low temperature resistance, etc., so that the material is widely used in general machinery, chemical machinery, food and paper and other fields, as easy to wear, corrosive, high impact, low temperature and can not be used in a variety of parts and materials lubricants bin liners, chute, chute liners, rails, fuel tanks and the like.
