Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Dupont Delrin is the best plastic for turning on a lathe lathe. It’s pretty easy to turn, but it requires reduced speeds. I’ve used this plastic to make Scottish small pipes chanters. I have bought many items from a plastic shop in Anaheim. The smaller pieces always 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 quite durable and easily machinable, and they have similar physical properties. They do appear similar, but for practical uses there are some 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 applicable properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got a very 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, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help 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 lasting dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in boating 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.
