Formula: POM-C
Form: Granule
Material: Polyoxymethylene Copolymer (POMc)
Commodity: Polymers
Nominal Granule Size:
3mm
Color:
Natural
POM Copolymer Granules are a thermoplastic polymer available in 14 variations with a wide range of applications across many industries. They offer high stiffness, low friction and good dimensional stability. These granules are commonly used in precision parts such as bearings, gears, rollers, and bushings. With their excellent sliding properties, POM Copolymer Granules are also widely used for medical devices and food processing equipment.
