Acetron® is a general purpose copolymer acetal and is the only porosity-free acetal product available today. Investments in process technology now provide the performance and machinability of acetal without center core porosity. The in-line photometric quality procedure assures every sheet and rod is porosity-free as measured by the dye penetrant test making it the preferred acetal for food contact and medical applications. Acetron GP ® natural is FDA, USDA, NSF, Canada AG, and 3A-Dairy compliant.
Acetal provides 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 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.
