Chemically known as Polyoxymethylene (POM), Acetal is a semi crystalline engineered thermoplastic. Acetal is one of the most commonly machined plastics throughout the world for variety of applications. It is often a great material choice because of it’s machine ability, rigidity, dimensional stability, low coefficient of friction and creep resistance.

There are two different types of Acetal; Homopolymer and Copolymer. Homopolymer goes by the trade name Delrin and Copolymer has a variety of trade names including but not limited to Tecaform, Acetron and Sustarin. The main difference between Homopolymer and Copolymer is that the Homopolymers is produced with a single type monomer, whereas copolymers are formed using two different types of monomers.

Features and Benefits of Acetal

Acetal is a highly crystalline rigid plastic that has a low coefficient of friction against metals, acetals and other plastics. Acetals do not absorb a large amount of moisture and are resistant to a wide range of solvents. It is creep resistant making it ideal for parts where dimensional stability is important.

Due to its FDA, NSF and 3A Dairy compliance Acetal is found in a variety of food, beverage and packaging applications. Acetal is also used in several other industries including agricultural, construction, automotive, conveyor technology and process engineering.
