Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Dupont Delrin is a great plastic for turning on a machine lathe. It’s easy to turn, however it requires slower speeds. I have used this material to make Scottish small pipes chanters. I have bought countless items from iPlastic. Smaller parts always ship quickly and everything was well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, and they have very similar physical properties. They look similar, but in practical use there are some differences that may make one better than the other. It also depends on your application. As with any plastic materials, make sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,as it gives an excellent finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the ideal 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 superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which help 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 term dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in moisture applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
