Compare and contrast Dupont Delrin and Acetal Copolymer in Sheet and Rods

Dupont Delrin is the best plastic for turning on a CNC lathe lathe. It’s easy to turn, but it requires slower speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. The small pieces usually ship quickly and everything has been 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 the same, but in practical use there are some differences that can make one better 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an great finish both on manual and CNC Machines. Its got 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is especially of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
