Acetal Natural (White)

What is Acetal?

Acetal copolymer is an engineering thermoplastic based on formaldehyde polymerization technology. Acetal copolymer resin is produced by a number of companies, including Celanese and BASF, which sell these products under their trade names of Celcon and Ultraform.

Acetal copolymer has an exceptional balance of tensile properties, shear strength, stiffness, and toughness. The toughness of this resin is evident in its high tensile yield strength. It is a natural bearing material because it exhibits a very low coefficient of friction against metals, and has excellent abrasion resistance.

The thermal properties are unusually good. It has excellent resistance to high intermittent temperatures and it retains its shape and physical integrity at elevated temperatures. The long-term stability at high temperature is outstanding. Additional thermal characteristics are its excellent retention of initial mechanical properties in hot air and hot water.

Electrical properties of Acetal copolymer include good dielectric strength, good dissipation factor, low dielectric constant over a range of frequencies, high volume resistivity, and excellent arc resistance. These properties exist with exceptional mechanical strength and heat resistance.

Acetal Sheets and Acetal Rods (aka POM) acetal copolymer 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 of its high strength, modulus, and resistance to impact and fatigue, Acetal is used as a weight-saving metal replacement. Acetal copolymer overcomes the common problem of centerline porosity in large shapes of Acetal Homopolymer (aka Delrin)
• Acetal Copolymer is preferred to Delrin (DuPont brand Acetal Homopolymer) where centerline porosity
is a concern.
• Acetal copolymer is produced under several brand names including Celcon, Ultraform & Acetron.
