What is Acetal?
Acetal (polyoxymethylene or POM) is a high strength, low friction, semi-crystalline engineering plastic with low moisture absorption. It has excellent wear and abrasion properties in both wet and dry environments. Easy to machine, acetal makes an outstanding choice for applications that require complex, tight tolerances.
What is the difference between acetal homopolymer Delrin® and acetal copolymer?
Homopolymer acetal Delrin®– has superior room temperature strength, stiffness, and toughness.
Copolymer acetal– has excellent performance in continuous high heat and hot water environments. It also tends to have less porosity than homopolymer acetal.
Why should I choose one acetal material over the other?
Delrin® 150– is the standard homopolymer acetal grade. It is available in a variety of colors.
Delrin® 511P– is a homopolymer acetal that offers enhanced crystallization characteristics. This higher level of crystallization helps to augment aspects of the physical properties such as fatigue strength, stiffness, and creep resistance.
Delrin® 100AF Blend, Delrin® AF DE588, and TECAFORM® HPV13– are homopolymer filled acetal enhanced bearing and wear grades.
Delrin® 570– is a glass-filled grade acetal that offers enhanced strength and stiffness.
Need a grade of acetal you don’t see here?FDA compliant, metal detectable, and x-ray detectable grades are available. Ask a plastics expert or get a quote.
How chemically resistant is acetal?Acetal plastics are chemically resistant to many fuels and solvents. View our comprehensive list of the chemical resistance of acetal.
What are common brands of acetal?Acetal is also known as Delrin®, SUSTARIN®, TECAFORM®, and Acetron®.
What are common acetal applications?Acetal is widely used for bearings and bushings, pump and valve parts, manifolds, gears, food processing and packaging machinery parts, wear pads, wear strips, and many other applications.
