Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod

Delrin is the best plastic for turning on a CNC lathe lathe. It is simple to turn, but it does require slow speeds. I use this plastic to make Scottish small pipes chanters. I have ordered countless items from Industrial Plastic. The small parts usually ship quickly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, as they have comparable physical properties. They appear similar, but for practical use there are some differences that can make one better 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,as it gives an excellent finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it outstanding 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 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 plastics chosen within the automotive industry because of its long term dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in boating applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
