Compare and contrast Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It’s very easy to turn, but it requires slower speeds. I have used this plastic to make Scottish small pipes chanters. I have bought numerous items from iPlastic. The small pieces always ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very tough and easily machinable, as they have comparable physical properties. They do appear similar, but in practical uses there are some differences that may make one better than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,giving an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal well because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
