Compare and contrast Copolymer Acetal and Dupont Delrin Homopolymer in Round rods or sheets and plate

Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s very easy to turn, although it requires reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. The small pieces always ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, as they have comparable physical properties. They do appear the same, 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 desired properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,giving an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, hardness and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics used within the auto industry because of its long lasting 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 the low moisture absorption results in components that will not expand or change dimensions due to contact with water.
