POM is a high-performance engineering plastic with similar hardness, strength, and steel properties to metals. It has excellent self-lubrication and chemical resistance over a wide range of temperature and humidity. POM, with a lower cost than many other engineering plastics, is replacing some markets traditionally occupied by metals, such as replacing zinc, brass, aluminum, and steel to make many components, and is widely used in fields such as electronics and electronics, machinery, automobiles, building materials, agriculture, and healthcare.
