Delrin® acetal resin

Delrin® - An Industry-Leading, High-Performance Acetal Resin

Delrin® acetal homopolymer combines lubricity and wear resistance with the stiffness and strength needed in parts designed to replace metal.

DuPont™ Delrin® acetal homopolymer resin is a highly-crystalline polymer that has high stiffness and strength without the need for glass reinforcement.  When compared to acetal copolymers offered by competitors, Delrin® offers higher tensile strength, stiffness, and creep resistance, and significantly outperforms on impact resistance, allowing for thinner and lighter part design.   In addition, Delrin® offers outstanding low- and high-temperature performance, good colorability, and good mating with metal and other polymers.

Delrin® provides dimensional stability in high precision molding and flexibility of design. From auto parts to innovative new medical devices, Delrin® is a premier choice for consumer and industrial solutions.
