Delrin® AF, Delrin® 100AF and Delrin® AF Blend belong to a family of PTFE filled DuPont acetal homopolymers. DuPont Delrin® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer. They are a unique subset of thermoplastic materials designed for use as bearing and wear components where low friction and long wear life are important. They are a combination of PTFE fibers (or PTFE powder) uniformly dispersed in Delrin® acetal resin. This combination offers better wear characteristics than unfilled Delrin® due to the presence of PTFE acting as a solid lubricant. Bearings made of Delrin® AF can operate at higher speeds while extending life to the component. Delrin® AF retains 90% of the strength that is inherent in unmodified Delrin®. Although there are other variations of PTFE filled acetal available, Delrin® AF Blend is widely available and generally speaking, less expensive.

Our team uses high performance thermoplastics to design and manufacture solutions — whether injection molded, machined, stamped, fabricated, or assembled — that exceed the demands of your specific applications so you can focus on product and market development.

Available in sheet, rod and tubing, it is easily machined with standard metal working equipment. Tolerances of +/-.001 can be achieved with experience.
