Comparing Dupont Delrin and Acetal Copolymer in Sheet and Rods
Delrin is the best plastic for turning on a lathe lathe. It’s pretty easy to turn, although it requires reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have ordered numerous items from a plastic shop in Anaheim. The smaller pieces always ship promptly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, and they have very similar physical properties. They do look the same, but for practical uses there are some differences that can make one preferable than the other. It also depends 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,giving 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 applications and is certainly of value 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 engineering plastics used within the auto industry because of its long term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Tecaform AH is in marine applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
