Acetal, also called polyoxymethylene (POM), polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts that require low friction, high stiffness, and excellent dimensional stability. Like many other synthetic polymers, it is manufactured by different chemical firms with slightly different formulas.
Acetal is categorized by its high strength, hardness, and rigidity. Acetal is intrinsically opaque white because of its high crystalline composition but can be produced in various colors.
Homopolymer and Copolymer are two different variations of acetal that have different properties and applications.
