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

Dupont Delrin is the perfect plastic for turning on a machine lathe. It is pretty easy to turn, although it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased many items from iPlastic. The smaller pieces always ship promptly and everything was well packed. I’ve 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 look similar, but for practical use there are a few differences that can make one better than the other. It also depends heavily on your application. As with all 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 probably our best material for machining,giving an nice 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 important. Acetal Sheet has the perfect combination of high mechanical strength, durability and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet 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.
