DELRIN® 100AF Blend


Delrin 100AF blend is a POM homopolymer with special PTFE fibers designed to optimize the material's sliding friction properties. The fibers are homogeneously distributed in the acetal material, which results in improved slide-friction performance 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.
