GF POM

Copolyoxymethylene

It is a kind of plate/bar made of fiber reinforced by polyformaldehyde material, which has higher mechanical strength and temperature resistance, creep resistance and dimensional stability than pure formaldehyde material. It can be used for a long time at temperatures from -40°C to 120°C.
