Acetal is a thermoplastic resin commonly used for injection molding applications. Acetal resins, or technically called polyoxymethylenes (POM), are among the strongest and stiffest of thermoplastics. Acetal copolymers are well known for their fatigue and wear resistance as well as high chemical resistance and dimensional stability.

Acetals are produced by the polymerization of purified formaldehyde into both homopolymer and copolymer types. Many involve replacement of metals where the higher strength of metals is not required and costly finished and assembly operations can be eliminated. Acetal resins provide an outstanding consistency of properties and color. They have exceptional solvent resistance, are virtually unaffected by strong bases, but are attacked by strong mineral acids. Acetals are rigid, creep resistant and strong. They possess low coefficients of friction, and remain stable at high temperatures, even for extended use.
