Our Acetal Copolymer Flat Washers or Spacers are made from natural and pigmented resins. Acetal Copolymer is a synthetic sheeting material that provides high strength and stiffness coupled with enhanced dimensional stability. Because of its high strength, modulus, and resistance to impact and fatigue, Acetal Copolymer is frequently used as a weight-saving metal replacement.
