Dupont Delrin is the best plastic for turning on a lathe lathe. It’s pretty easy to turn, but it does require slower speeds. I have used this plastic to make Scottish small pipes chanters. I have bought numerous items from iPlastic. The smaller pieces always ship promptly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, as they have comparable physical properties. They do look similar, but in practical uses there are a few 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 desired properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,as it gives an great finish both on manual and CNC Machines. It has a very 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 strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is especially valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics chosen within the auto industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
