Acetal - Acetron, Delrin
Acetal provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, it is also characterized by a low coefficient of friction and good wear properties - especially in wet environments. Because Acetal absorbs minimal amounts of moisture, its physical properties remain constant in a variety on environments. Low moisture absorption results in excellent dimensional stability for close-tolerance machined parts. Acetal is ideally suited for close tolerance mechanical parts and electrical insulators which require strength and stiffness and also offers resistance to a wide range to chemicals including many solvents.
