What the difference between Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod

Dupont Delrin is a great plastic for turning on a CNC lathe lathe. It is very easy to turn, however it does require slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have ordered countless items from iPlastic. 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 very similar physical properties. They do look the same, 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, be 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,giving an great 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 critical. Acetal Sheet has an ideal 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 especially 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 aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics chosen within the auto industry because of its long term dimensional stability and durability. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Sustarin C is in boating applications. This environment suits acetal well because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
