Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod
Delrin is the best plastic for turning on a machine lathe. It’s easy to turn, but it does require slow speeds. I use this plastic to make Scottish small pipes chanters. I have ordered many items from iPlastic. The small pieces usually ship quickly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, as they have very similar physical properties. They appear similar, but for practical use there are some differences that may make one preferable than the other. It also depends heavily on your application. As with all plastic materials, be 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,giving 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 important. Acetal Sheet has the perfect 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 especially 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 auto industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
