Compare and contrast Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate

Dupont Delrin is a great plastic for turning on a machine lathe. It’s easy to turn, however it requires slow speeds. I’ve used this material to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Smaller pieces always ship promptly and everything was 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, and they have comparable physical properties. They look similar, but for practical uses there are a few differences that can make one preferable than the other. It also depends heavily on your application. As with all 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 probably our primary material for machining,as it gives an great finish both on manual and CNC Machines. Its got a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the auto industry because of its long lasting dimensional stability and durability. It delivers 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 the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
