Acetal plastic, also called polyacetal and polyoxymethylene (POM), is a general purpose, semi-crystalline,engineered thermoplastic. Acetal is commonly used for parts that need to be very stiff, have low surface friction and good dimensional stability. Dimensional stability is the ability of a plastic part to maintain its original dimensions when it is exposed to changes in temperature and humidity.
What is an engineered plastic?
Engineered plastics have better mechanical properties and handle heat better than commodity plastics. This makes them tougher and more suitable for extreme environments. Commodity plastics are simply not as tough. Some familiar commodity plastics are PVC, polyethylene and polypropylene.
POM for Injection Molding
: Widely used in the automotive and consumer electronics industry.
