Plastic Machining with Acetal and Delrin Plastic

Pete Poodiack, VP of Sales and Marketing at Controlled Fluidics, talks about Acetal and Delrin plastics and what makes them popular materials for plastic machining and fabrication.

Welcome. In this video, we’re going to talk about two of our most popular materials at Controlled Fluidics, and that’s Acetal and Delrin.

Acetal is a copolymer, while Delrin is a homopolymer. They’ve both tough FDA-compliant materials used for similar purposes. They offer excellent mechanical, electrical, and wear properties as well as low creep and good dimensional stability.

Acetal and Delrin both have high melting points. They can handle continuous temperatures of up to 185 degrees Fahrenheit and burst exposure of up to 200 degrees. They’re also resistant to most solvents, but you need to avoid high concentrations of acids or bases.

The most significant difference between these materials is that Delrin has slightly better wear qualities than acetal, and that’s the deciding factor between these materials for some projects.

Now let’s talk about applications.

At Controlled Fluidics, we find that our clients like to use these materials for bearings because they have a low coefficient of friction, and they wear well in wet or dry applications. Acetal and Delrin are also great for electrical components because they have high dielectric strength and low moisture absorption. We also see this material used in medical devices and on machine parts for the food industry.

This only covers the basics. Learn more about Acetal and Delrin Plastics on our materials page.
