Delrin® AF DE588 is a 20% PTFE filled homopolymer acetal that is fully tested and certified for use by the United States Navy. The resin is manufactured by DuPont and is used extensively in a variety of applications primarily on submarines.
This advanced acetal material uses a combination of PTFE fibers uniformly dispersed in Delrin acetal resin. The combination results in improved wear characteristics along with strength, toughness, dimensional stability and machinability. The profile also yields a material with superior load bearing capabilities, especially when operating at high speeds.
At Emco Industrial Plastics, Delrin® AF DE588 is part of our extensive line of engineered resin solutions for industrial, marine, and defense applications. Whether you need stock material or support identifying the right engineering plastic, our team is ready to help you find a solution that matches your application.
The performance of Delrin® AF DE588 comes from combining the strength of delrin material with the low-friction properties of PTFE material. The acetal base provides excellent rigidity, dimensional stability, and machinability, while the PTFE fibers are evenly dispersed throughout the material to reduce friction and wear during operation.
This combination supports smooth movement between contacting surfaces and helps extend the service life of machined components. It is an effective choice for applications where repeated motion, heavy loads, and dependable long-term performance are expected.
Delrin® AF DE588 is selected for projects where standard acetal materials may not provide the required wear performance. Its material properties make it suitable for precision-machined components operating under demanding conditions.
As part of Emco Industrial Plastics' selection of engineered resin solutions, Delrin® AF DE588 gives manufacturers access to a proven material for demanding industrial and military applications.
Although Delrin® AF DE588 is widely recognized for its use in United States Navy submarine programs, its performance benefits also make it suitable for many commercial and industrial applications. Manufacturers use this material for bearings, bushings, valve seats, seals, and other precision components that experience continuous movement or friction.
The combination of delrin material and PTFE material helps reduce wear while maintaining the strength needed for demanding operating conditions. This makes Delrin® AF DE588 a practical option for marine equipment, industrial machinery, fluid handling systems, and other equipment where reliability is a priority.
Emco Industrial Plastics supplies premium engineered resin solutions supported by knowledgeable service and dependable material availability. We understand that selecting the right engineering plastic can affect performance, production efficiency, and long-term operating costs.
Whether you need stock shapes for machining or assistance identifying the right delrin material for your application, our team can help you choose a material that fits your performance requirements.
