POM is a highly crystalline polymer with smooth and shiny surface, small water absorption, stable size, wear resistance, high strength, good self-lubrication, good coloring, oil resistance and peroxide resistance. POM has good comprehensive properties, is hard among thermoplastics, and is one of the types of plastic materials whose mechanical properties are close to those of metals. Its tensile strength, bending strength, fatigue resistance, wear resistance and electrical properties are very good. , can be used for a long time between -40°C--100°C.
The injection pressure of POM with Teflon is generally 750-1250bar, which is only used for product design and materials. Teflon pom plastic is translucent or opaque milky white or yellow particle shape, crystallized to form a polymer, which is plastic.
POM is widely used in the manufacture of various sliding and rotating mechanical parts, as various gears, levers, pulleys, sprockets, especially suitable for bearings, hot water valves, precision metering valves, chain rings and rollers of conveyors, flow meters, automobiles, etc. Internal and external handles, cranks and other window rotating machinery, oil pump bearing housings and impeller gas switch valves, electronic switch parts, fastening bodies, terminal mirror masks, electric fan parts, heating plates, instrument buttons; various pipelines and agricultural sprinkler irrigation systems and Valves, nozzles, faucets, bath tub parts; switch keyboards, buttons, temperature control timers; power tools, garden finishing tool parts; in addition, it can be used as surfboards, sailboats and various sled parts, watch micro gears, sports equipment Various buckles, fasteners, lighters, zippers, buckles, crowns, prostheses, etc. for frame accessories and backpacks
