Polyacetal POM

Polyacetal is a resin material with well-balanced mechanical properties.

There are two products-homopolymer and copolymer-that have differing molecular structures, and we offer four copolymer products in our lineup.

Difference between polyacetal homopolymers and polyacetal copolymers (Difference of molecular structures)

    • Homopolymer
    • -CH2O- repetitive main chain
    • Copolymer
    • -C-C- structure intervenes
