Acetal Sheets and Acetal Rods (aka POM) acetal copolymer provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, acetal is also characterized by a low coefficient of friction and good wear properties especially in wet environments. Because of its high strength, modulus, and resistance to impact and fatigue, Acetal is used as a weight-saving metal replacement. Acetal copolymer overcomes the common problem of centerline porosity in large shapes of Acetal Homopolymer (aka Delrin)
Acetal Copolymer is preferred to Delrin® (Acetal Homopolymer) where centerline porosity is a concern.
Acetal Copolymer is produced under several brand names including Celcon®, Ultraform® & Acetron®.
