Comparing Dupont Delrin and Acetal Copolymer in Sheet or Plate and Round Rod
Dupont Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, but it does require reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have ordered countless items from iPlastic. The small pieces usually ship promptly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, and they have very similar physical properties. They appear similar, but in practical uses there are a few differences that can make one better than the other. It also depends on your application. As with any 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 probably our primary material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is especially of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve 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 engineering plastics chosen within the automotive industry because of its long lasting dimensional stability and durability. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that wonâ€™t expand or alter dimensions due to contact with water.
