Overview
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. Also, it mates well with metals and other polymers and offers excellent dimensional stability in high precision molding, greater tensile strength, stiffness, creep and fatigue resistance, as well as 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.
