Product Details

Product Description:

1 Polyoxymethylene(POM plastic raw materials), also known as acetal , polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability.

2 Properties

POM is characterized by its high strength, hardness and rigidity to -40 °C. POM is intrinsically opaque white, due to its high crystalline composition, but it is available in all colors.

POM homopolymer is a semi-crystalline polymer (75-85% crystalline) with a melting point of 175° Celsius

POM copolymer has a slightly lower melting point of 162 – 173° Celsius.
