Acetal: Tougher Than You Think

Truly versatile, high-performance materials, acetal homopolymer and copolymer resins can be used in a wide range of applications.

Although many compounds have an acetal function group, polyoxymethylene is most commonly referred to as “acetal.” A homopolymer, which means the same molecular unit repeats throughout the polymer chain, polyoxymethylene specifically features a very high melting point and superior liquid resistance, making it ideal for use in plumbing, piping, and marine applications.

Why Choose Acetal?

The single greatest strength of acetal, and polyoxymethylene in particular, is its incredible versatility, allowing it to be used in many varied scenarios — everything from guitar pick fabrication to petrochemical processing.


Acetal also has superior flexural and tensile strength, as well as excellent hardness and dimensional stability. Its fatigue resistance is very high, as is its lubricity and creep resistance. Because none of these properties are compromised when exposed to a range of operating temperatures, acetal is commonly used to fabricate engines and motors. Acetal stamping is also frequently employed to make gears, cams, bushings, and other critical mechanical components.

With superior corrosion resistance, acetal homopolymers can resist corrosion and degradation when submerged in fresh water, salt water, solvents, oils, reagents, and alkalis. The only real exception is mineral acid solutions — over time, hydrochloric, nitric, and sulfuric acids can have corrosive effects.

Acetal homopolymers also feature strong electrical properties and can be used in a wide range of electrical applications.
