Comparing Dupont Delrin and Acetal Copolymer in Sheet and Rods

Delrin is the best plastic for turning on a CNC lathe lathe. It’s very easy to turn, but it does require reduced speeds. I use this material to make Scottish small pipes chanters. I have ordered many items from iPlastic. Smaller pieces usually ship quickly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have comparable physical properties. They look similar, but for practical use there are some differences that can make one better than the other. It also depends heavily on your application. As with any plastic materials, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,giving 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 important. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics used within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in boating applications. This environment suits acetal well because the low moisture absorption results in components that will not expand or change dimensions due to contact with water.
