Polyoxymethylene, also known as polyoxymethylene (POM), is a white, opaque, crystalline linear thermoplastic resin with excellent overall properties and coloring capabilities. It boasts high elastic modulus, exceptional rigidity and hardness, and strength and stiffness close to those of metals. POM exhibits superior tensile strength, flexural strength, resistance to creep and fatigue, and excellent resistance to repeated impacts and unloading recovery. It has a low coefficient of friction, good wear resistance, excellent dimensional stability, a glossy surface, high viscoelasticity, and excellent electrical insulation properties, unaffected by temperature. It also has good resistance to insulation and is unaffected by humidity. POM is highly resistant to chemicals, stable against most substances except strong acids, phenols, and organic halides, and is oil-resistant. Its mechanical properties are minimally affected by temperature, and it has a high heat deflection temperature.
