POM+PTFE30%

Copolyoxymethylene

POM+PTFE30% is a blend of POM and Teflon material, which retains most of the strength of POM. Due to the change of material properties after adding Teflon, the material becomes softer, less rigid, and the surface becomes smoother.

Advantage

Characteristic：

1. Low friction coefficient, wear resistance, and basically no creep phenomenon, good creep resistance; Even at low temperatures, the impact strength is high.

2. Very good dimensional stability; The sliding property is better than pure POM, and the mechanical property is excellent. Physiological inertia, suitable for contact with food.
