Acetal

Acetal (POM) - A thermoplastic produced by the addition polymerization of an aldehyde through the carbonyl function, yielding unbranched polyoxymethylene chains of great length. The acetal resins are among the strongest and stiffest of all thermoplastics, and are characterized by good fatigue life, low moisture sensitivity, high resistance to solvents and chemicals, and good electrical properties. Because of these properties, acetals often compete with nylons for many of the same applications. Acetals may be processed by conventional injection molding and extrusion techniques. The main area of application for acetal is industrial and mechanical products.

The acetal polymer (POM) class was first introduced in 1956 and has achieved important application because of a good profile of properties. Two types of acetals available are a homopolymer and a copolymer with slightly different advantages for each. Acetals are available in fiber reinforced and lubricated molding grades as well as extruded shapes for machined parts.
