Acetal Copolymer resin is prized for its high strength, rigidity, toughness, and dimensional stability. It also has good wear and friction properties that can be improved by compounding with additives.

Like Acetal Copolymer resin, copolymer is easy to machine. However, Acetal Copolymer resin exhibits better resistance to organic and inorganic solvents and acids than Acetal Copolymer.

What Are the Mechanical Properties of Acetal Copolymer?

Acetal Copolymer is easily machined with conventional metalworking equipment and can be machined to very close tolerances.

What Are the Disadvantages of Using Acetal Copolymer?

The disadvantages of Acetal Copolymer resin include its longer molding cycle times, its sinks, and the relatively high cost of the thermoplastic.

Acetal Copolymer is non-hygroscopic and usually is FDA, USDA, Canada AG, and 3A-Dairy compliant. It absorbs minimal amounts of moisture and can be easily cleaned. As a result, it is used for environments with high humidity or moisture, food handling, and medical and marine components.

Although Acetal Copolymer has many benefits as an unfilled material, it can be filled with solid lubricants to enhance its bearing and wear properties. In addition, Acetal Copolymer have excellent resistance to chemicals and solvents.

How is Acetal Copolymer Made?

To make Acetal Copolymer, the polyoxymethylene copolymer replaces about 1–1.5% of the −CH2O− groups with −CH2CH2O−.
