Polyoxymethylene (POM)

Polyoxymethylene (POM)

  • Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. As with many other synthetic polymers,
  • Typical applications for POM include high performance engineering components such as small gear wheels, ball bearings, ski bindings, fasteners, knife handles, and lock systems. The material is widely used in the automotive and consumer electronics industry



  • high dimensional stability
  • low absorption of moisture
  • outstanding sliding properties
  • high abrasion resistance
  • ideal combination of tensile strength, stiffness and impact strength
  • low creep tendency
  • good machinability
  • favourable electric and dielectric behaviour
