Delrin® Outlasts Acetal Copolymer in Slap Test

DuPont™ Delrin® acetal homopolymer goes head-to-head against acetal copolymers in the "slap test". Watch to see which material outlasts the other.

Delrin® acetal (Polyoxymethylene POM) combines low friction and high wear resistance with the stiffness and strength needed in parts designed to replace metal. It provides a wide operating temperature range (-40°C to 120°C), good colorability and good mating with metal and other polymers, as well as dimensional stability in high precision molding.

When compared to acetal copolymer, Delrin® acetal homopolymer offers higher tensile strength, stiffness, and creep resistance, and significantly higher impact resistance, allowing for thinner and lighter part design, shorter molding cycles and the potential for cost reductions.
