Short Description:

Polyoxymethylene (POM), also known as acetal resin, polyoxymethylene resin, and polyacetal, is a thermoplastic crystalline polymer, reputed as “super steel” or “better steel”. As one of the five general engineering plastics, POM has high mechanical properties, such as strength, modulus, abrasion resistance, toughness, fatigue resistance, and creep resistance, as well as excellent electrical insulating property, solvent resistance property, and processability.
