Polyoxymethylene(POM): is also commonly known as (Poly)acetal, POM is a kind of Semi-crystalline Polymers, strong, has nice rigidity and high mechanical strength, which means it is widely used in different industrial usages.

POM is an acronym for the chemical name polyoxymethylene. It is generally referred to as polyacetal or acetal resin. It is a crystalline thermoplastic resin comprised chiefly of (-CH2O-) structural units.

It is mainly used in applications centered on mechanical components such as gears, screws, and bearings, and in important parts requiring chemical and heat resistance. Examples of its use can be found far and wide, from AV equipment such as DVD recorders and Blu-ray disk recorders, office equipment such as printers and copiers, household appliances such as washing machines, refrigerators and electric shavers, automotive parts such as door locks, fuel caps, fuel pump modules, seat belt mechanical components and interior parts, to household equipment such as window sashes and blinds, and toys such as the latest gaming devices.
