Specific properties of POM-H AF plastic

POM-H AF – 10% PTFE filled is designed to optimize the material’s sliding friction properties has a very high toughness to it and is resistant to cleaning agents. The fibers are homogeneously distributed in the acetal material which means that it has improved the slide-friction coefficient and abrasion resistance, not to mention the minimal susceptibility to stick-slip effects. POM-H AF plastic also provides good creep strength and great dimensional stability.
