PlasticsPolyoxymethylene (POM)


Polyoxymethylene (POM) is a semi-crystalline thermoplastic.


Polyoxymethylene has been on the market since 1956.

Structure and properties:

POM H (homopolymer)
Chemically, the polymer differs from paraformaldehyde mainly in its degree of polymerization. To stabilize it and prevent depolymerization under acid influence or thermal stress, the end groups are closed by etherification or esterification.

POM C (copolymer)

Another possibility for stabilization against acid influence and thermal stress is the production of copolymers, which is achieved by copolymerization of trioxane with dioxane.
