POM plastic is similar to nylon, but POM is harder and having a bigger density, low noise, and low friction force. POM plastic can be used between -40-130ºC. POM plastic is better than most industrial plastic on anti-friction and self-lubrication, but having good anti-oil and anti-peroxide performance at the same time.Polypropylene (PP) plastic has low density (lower than water), low hygroscopicity, and high melting point among all the hot plastics, good insulation, and low dielectric value.  it also has good anti-chemical performance, such as acid, alkali, ethyl alcohol, inorganic substance, salt solution, gasoline, water, petroleum, grease, detergent, juice, milk and etc., but it has no resistance for aromatic hydrocarbon and chlorate.It has good anti-alkali performance and has good adaption for petroleum products and all neutral character chemical products.Dihui ball is called "Plastic King", which is famous for anti-friction, and it has several Chinese names. Dihui ball has excellent chemical stabilization (anti-rust, high-lubrication, solution and anti-aging and etc.). It can be continuously used between -180ºC to 250ºC. Dihui ball balls are famous for not having fiction.Polyether-ether-ketone (PEEK) is a good performance industrial special plastic. It has good anti-friction and self-lubrication performation in comparison with other special plastic. Besides, it can bear high pressure and has low creep property. It also has good mechanical performance, such as high-temperature resistance, anti-chemical corrosion, anti flaming, anti-stripping, anti irradiation, isolation, anti hydrolyzing, easy to process and etc.ApplicationMainly bearing used on the sliding devices of tables or drawers, bearings, rollers, valves, electronic devices, sailboats and etc.cosmetic bottles, oil, acid and alkali, and some other liquid.Back-pressure valves, light carriers, rotary knobs, switches, some other low cost but the high requirement on elasticity/hardness applications.Mainly on low-temperature liquid and acid instruments.Mainly on petrochemical, electronics, bearing sealing, instruments and apparatus, automotive industry, aerospace, ship, nuclear, and other high requirement industry.
