How to compare Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate

Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s simple to turn, however it does require slow speeds. I use this stuff to make Scottish small pipes chanters. I have ordered countless items from iPlastic. The smaller pieces always ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, as they have comparable physical properties. They look the same, but for practical uses there are a few differences that may make one preferable than the other. It also depends heavily on your application. As with any plastic materials, make sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, hardness and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent 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 auto industry because of its long lasting dimensional stability and toughness. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in water applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
