POM (Polyoxymethylene) is an engineering thermoplastic material that demonstrates excellent dimensional stability, stiffness and impact and temperature resistance. The material, also known as acetal or Delrin, can be produced two ways: as a homopolymer or as a copolymer.

POM materials are commonly used in the fabrication of pipe components, gear bearings, household appliances, automotive parts, consumer electronics and more.
