Delrin 100AF

DuPont Delrin® AF100 Blend acetal is a unique thermoplastic material for use in moving parts in which low friction and long wear are important. It is a combination of Teflon® fibers uniformly dispersed in DuPont Delrin® acetal resin. This combination produces a material that has strength, toughness, dimensional stability and good machinability, plus improved wear characteristics over unfilled DuPont Delrin®.

Bearings made of DuPont Delrin® AF100 Blend sustain high loads when operating at high speeds and show reduced wear. These bearings are also essentially free of slip-stick behavior because the static and dynamic coefficients of friction are closer than with most plastics. DuPont Delrin® AF100 Blend retains much of the strength that is inherent in unmodified DuPont Delrin® acetal. Some properties are changed due to the addition of the softer Teflon® fiber. The natural color of DuPont Delrin® AF100 Blend is dark brown.
