Polyoxymethylene (POM)

POM (Polyoxymethylene), also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts which require high stiffness, low friction and excellent dimensional stability. As a tough, solvent and fuel resistant plastic it is used for gears, bearings, window guides, speaker grills, zips, lighters, aerosol valves, fasteners and furniture components.
