Acetal (POM) 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.
Copolymer acetal is preferred to Delrin where centerline porosity is concerned.
Acetal copolymer resin is produced under several brand names including Celcon & Ultraform.
