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.

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.
This copolymer acetal grade, containing a metal detectable additive, has been specifically tailored for use in the food processing and packaging industries where it can easily be traced by the conventional metal detection systems installed to detect contamination of the foodstuffs (results may vary depending on the sensitivity of the metal detection system used). Acetron MD presents good mechanical strength, stiffness and impact strength, and it also features a food contact compliant composition.
Acetron® LSG (POM-C) stock shapes are produced from selected batches of polyacetal copolymer resin. This engineering plastic combines good mechanical strength, stiffness, impact strength, chemical resistance, dimensional stability and friction and wear properties with an excellent machinability.
