Acetal

Acetal (POM) 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.

Copolymer Acetal provides excellent performance and machinability without center core porosity, which lends itself as a preferred material for food contact and medical applications. Acetal comes standard in black and white, with the latter being FDA, USDA, NSF, Canada AG and 3A-Dairy compliant.

Material is available in Sheet, Rod, Tube, Hex & Square.

Dissipative Acetal

Static dissipative Acetal is designed for use where electrical discharge in operation is a problem. This properties of this material are ideal for fixturing used in the manufacturing of hard disk drives or for handling in-process silicon wafers. It is tan in color. Surface resistivity: 1010 – 1016 ?/ sq. Thermal performance to 225°F (107°C) Good wear resistance.

Material is available in sheet and tube form.
