Engineering Thermoplastics
POM Copolymer — Polyoxymethylene Copolymer
POM copolymers offer a broader chemical resistance, especially to alkaline media, compared to homopolymers. They maintain excellent mechanical properties like stiffness, strength, and creep resistance, with slightly lower heat deflection temperatures and tensile strength.
