Acetal Sheets are of the plastics chosen within the auto industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal quite because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
Dupont Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s simple to turn, however it does require slow speeds. I’ve usedII have used this material Acetal versus Delrin to make Scottish small pipes chanters. I have bought many items from iPlastic. The smaller pieces 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 exceptionally durable and easily machinable, as they have similar physical properties. They look similar, but for practical uses there are some differences that can make one better than the other. It also depends heavily on your application. As with all plastic materials, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
