Comparing Dupont Delrin and Acetal Copolymer in Sheet and Rods

Dupont Delrin is the best plastic for turning on a machine lathe. It’s simple to turn, but it requires slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. Small parts usually ship quickly and everything is always 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 comparable physical properties. They look similar, but in practical use there are some differences that may make one preferable than the other. It also depends heavily on your application. As with any plastic materials, make 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 excellent finish both on manual and CNC Machines. It has 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, durability and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them create 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 will not expand or change dimensions due to contact with water.
