Dupont Delrin is a great plastic for turning on a lathe lathe. It is simple to turn, although it does require slower speeds. I use this plastic to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. The smaller parts always ship promptly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, as they have similar physical properties. They appear similar, but for practical use there are a few differences that may make one preferable 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 desired properties you may need for your application.
Our Acetal Sheet is definitely 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 critical. Acetal Sheet has the best 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 especially of value 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 automotive 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 water applications. This environment suits acetal quite because its low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
