Delrin® 13% AF blend, supplied as a 2:1 blend of Acetal AF-100 and Acetal 150 resins, has excellent friction properties. Bearings made of Acetal 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 are closer than with most plastics. Acetal AF blend retains 90% of the strength that is inherent in unmodified Acetal. Some properties are changed due to the addition of the softer PTFE fiber. The natural color of Acetal AF blend is dark brown.
