Delrin 150, also known as POM, polyoxymethylene or acetal, is a plastic material used in CNC machining, with high rigidity and strength.
Material Properties and Applications for Delrin 150
Due to its strength and rigidity, Delrin is great for machining gears, bearings, and fixtures.
Delrin is moisture and wear-resistant, as well as high-lubricity (slippery). That means glue and paint won't adhere very well to this material, so keep that in mind. Delrin can also be sensitive to high temperatures.
