Comparing Dupont Delrin and Acetal Copolymer in Sheet or Plate and Round Rod
Dupont Delrin is the best plastic for turning on a CNC lathe lathe. It is easy to turn, but it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have bought numerous items from iPlastic. The smaller pieces usually ship promptly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, as they have very comparable 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 on your application. As with all plastic materials, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,as it gives an excellent finish both on manual and CNC Machines. Its got a pretty 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb sliding abilities which help 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 delivers solutions for designers to help them produce 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 results in components that will not expand or alter dimensions due to contact with water.
