Comparing Acetal Copolymer and Dupont Delrin in Round rods or sheets and plate

Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It’s simple to turn, however it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have ordered many items from a plastic shop in Anaheim. Small parts always ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have comparable physical properties. They appear similar, but in practical use there are some differences that can make one preferable than the other. It also depends on your application. As with any 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,as it gives an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics chosen within the auto 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 sheet Acetal is in water applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
