POM ̶ polyoxymethylene

The POM material, commonly referred to as acetal, is a semi-crystalline thermoplastic with high mechanical strength and stiffness. POM has good sliding properties, excellent wear resistance and shows equally low moisture absorption. Good dimensional stability and extremely good fatigue strength combined with excellent machinability make it a universal construction material, even for complex components.


In terms of properties, a distinction is made between acetal homopolymers (POM-H) and acetal copolymers (POM-C). Due to its higher crystallinity, POM-H is characterized by slightly higher density, hardness and strength. However, the POM C material offers higher chemical resistance and a lower melting point than POM-H. The company AFINIS Group® sells POM material in the form of standard warehouse semi-finished products in the form of sheets, tubes and rods intended for processing.
