POM-C

Acetal Copolymer

Product Description：

White/Black

POM-C, Hostaform C, Ultraform, POM, Polyxymethylene, the high surface strength is only sur-passed by a few materials. POM shows good sliding properties and high resistance to wear and tear because of the high strength and smooth surface. There is a very low risk of stress crack. POM-C (Copolymer) exhibits a high thermal stability and a high resistance to chemicals (high resistance to hydrolysis).

Advantages
★no micro porosity
★high strength
★high rigidity
★high thermal stability
★good electrical insulation properties
★very good sliding properties
★high resistance to solvents
★very high resistance to stress cracks

Disadvantages
☆not resistance to high-concentrated acids
☆difficult to glue and paint
