Acetal Square Bars provide 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 Square Bar Stock is used as a weight-saving metal replacement. Parts made from Acetal copolymer overcome the problem of centerline porosity in large shapes of Acetal Homopolymer (aka Delrin) Sold in Standard 10 foot lengths – May be cut-in-half for shipping
