Delrin® AF DE588 is a specialized grade of acetal homopolymer (POM) resin, manufactured by DELRIN USA LLC. It is filled with 20% polytetrafluoroethylene (PTFE) fibers, which are uniformly dispersed throughout the material to enhance its performance properties. This results in a dark brown-colored (natural) thermoplastic that offers superior wear resistance, a low coefficient of friction, and improved dimensional stability compared to standard Delrin® acetal.

Key Features and Benefits:

• Military Certification: Fully tested and certified for use by the United States Navy under specifications such as NAVSEA 6959311 Rev. B and NAVSEA 803-4384678. It meets ASTM D6778
