Why you may choose either Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s easy to turn, however it requires reduced speeds. I’ve used this plastic to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. Small parts always ship quickly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, and they have very comparable physical properties. They do appear similar, but for practical use there are some differences that can make one preferable 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 definitely our primary material for machining,as it gives an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics chosen within the automotive industry because of its long term dimensional stability and durability. It provides 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 quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
