Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod
Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It’s easy to turn, although it requires slow speeds. I use this plastic to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. Small parts always ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are incredibly tough and easily machinable, as they have very comparable physical properties. They look similar, but for practical uses there are some differences that can make one better 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 applicable properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,giving an excellent 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, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics chosen within the automotive industry because of its long term 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 marine 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.
