Comparing Acetal Copolymer and Dupont Delrin in Sheet and Rods

Dupont Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, however it does require reduced speeds. I have used this material to make Scottish small pipes chanters. I have ordered countless items from iPlastic. The smaller pieces usually ship promptly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have very similar physical properties. They do look the same, but in practical use there are some differences that can make one preferable 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,as it gives an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the auto industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
