PTFE enhanced/filled Acetal Homopolymer

Delrin® AF Blend is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It is a combination of PTFE fibers uniformly dispersed in Delrin® acetal resin. This combination offers better wear characteristics than unfilled Delrin®.

Delrin® AF Blend, supplied as a 2:1 blend of Delrin® AF100 and Delrin® 150 resins, has excellent sliding/friction properties. Bearings made of Delrin® AF Blend can operate at higher speeds while exhibiting reduced wear. These bearings are also essentially free of slip-stick behavior because the static and dynamic coefficient of friction is closer than with most plastics.

Delrin® AF Blend retains 90% of the strength that is inherent in unmodified Delrin acetal. Some properties are changed due to the addition of the softer PTFE fiber. The natural color of Delrin® AF Blend is dark brown.
