Acetal products absorb a minimal amount of moisture, and their physical properties remain constant in a variety of environments. Acetals are easily machined and have excellent dimensional stability for close-tolerance machined parts. Acetal is ideally suited for applications which require strength and stiffness. Acetal shapes are produced from copolymer (Acetron® GP) and homopolymer (Delrin®) resins which provide a high modulus of elasticity coupled with great strength, stiffness and toughness. They are also characterized by a low coefficient of friction and good bearing characteristics.
