Polyoxymethylene (POM) is a high-performance engineering plastic that possesses metal-like hardness, strength, and rigidity. It exhibits excellent self-lubricating properties, good fatigue resistance, and elasticity across a wide range of temperatures and humidity levels. In addition, it has good chemical resistance. POM is widely used in the manufacture of various sliding and rotating mechanical parts, such as gears, levers, pulleys, and sprockets. It is particularly suitable for bearings, hot-water valves, precision metering valves, conveyor chains and rollers, flow meters, as well as automotive interior and exterior handles, cranks, and window operating mechanisms.
