Acetal provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-Acetal Gearcrystalline material, acetal 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 of environments. Low moisture absorption results in excellent dimensional stability for close-tolerance machined parts. In high moisture or submerged applications, acetal bearings outperform nylon 4 to 1. Acetal is ideally suited for close tolerance mechanical parts and electrical insulators which require strength and stiffness. It also offers resistance to a wide range of chemicals including many solvents.
