Formula: POM-C
Form: Foil/Film/Sheet
Material: Polyoxymethylene Copolymer (POMc)
Commodity: Polymers
POM Copolymer films are engineering plastic films available in 32 variations. They’re made from polyoxymethylene (POM) copolymers with their key properties being high stiffness, hardness and thermal stability. POM Copolymer films are commonly used for small precision parts, food processing equipment, bearings, gears, rollers, and bushings that require excellent wear resistance. With a wide choice of different dimensions, colors and surface finishes available, our range of POM Copolymer films provide options to suit an array of engineering applications.
