The High-Performance Acetal Resin

Red mechanical gears

Leading companies across the globe specify Delrin® acetal homopolymer from DuPont for high-load mechanical applications such as gears, safety restraints, door systems, conveyor belts, healthcare delivery devices, and other demanding products and parts.

Delrin® acetal homopolymer (Polyoxymethylene POM) is the ideal material in parts designed to replace metal. It combines low-friction and high-wear resistance with the high strength and stiffness such applications require. It provides a wide operating temperature range (-40 °C to 120 °C) and good colorability. Delrin® also mates well with metals and other polymers and offers excellent dimensional stability in high precision molding.

Compared to acetal copolymer, Delrin® acetal homopolymer offers higher tensile strength, stiffness, creep and fatigue resistance, and significantly higher impact resistance. The combination of these excellent mechanical properties in a single material allows for thinner, lighter-weight parts and shorter molding cycles with potential cost reductions.

Authentic Delrin® acetal homopolymer is available exclusively from DuPont, authorized DuPont distributors, and from stock shape suppliers in a variety of forms (sheets, rods, tubes).
