What the difference between Dupont Delrin and Acetal Copolymer in Sheet and Rods

Delrin is the best plastic for turning on a lathe lathe. It is very easy to turn, however it requires reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased countless items from iPlastic. Small pieces usually ship promptly and everything has been 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, and they have very similar physical properties. They do appear the same, but for practical use there are a few differences that can make one preferable than the other. It also depends on your application. As with any 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 definitely our best material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one 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 create long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal well because its low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
