Machined part
Customised profile
TECAFORM AD AF natural is a POM homopolymer with special PTFE fibres designed to optimize the material's sliding friction properties. The fibres are homogenously distributed in the acetal material, and results in an improved slide-friction coefficient and abrasion resistance, coupled with minimal susceptibility to stick-slip effects. Furthermore, the POM-H AF provides good creep strength and extremely good dimensional stability.
