POM (polyacetal,polyoxymethylenes,cas no:66455-31-0) is an excellent engineering plastics, in foreign countries have "wins Steel", "super steel" is called. pom metals with similar hardness, strength and steel, and in a very wide range of temperature and humidity have a good self-lubricating, good fatigue resistance, and flexible, in addition it also has good chemical resistance character. pom below the cost of many other engineering plastics are alternatives which are traditionally occupied by the metal markets, such as alternative zinc, brass, aluminum and steel production in many parts, since its inception, pom has been widely used in electronic and electrical, mechanical , instruments, daily-use light industrial, automotive, building materials, agriculture and other fields. In many new fields of applications such as medical technology, sports equipment, etc., pom also showed good growth.

 POM has a very low coefficient of friction and good geometric stability, particularly suited to the production of gears and bearings. It also has properties as a result of high temperature, it is also used pipe device (pipe valves, pump casing), lawn equipment, etc.
