Compare and contrast Copolymer Acetal and Dupont Delrin Homopolymer in Round rods or sheets and plate
Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It is very easy to turn, although it requires slower speeds. I use this plastic to make Scottish small pipes chanters. I have purchased countless items from iPlastic. The small pieces usually ship promptly and everything was well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, as they have very comparable physical properties. They look similar, but in practical use there are some differences that may 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely 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 critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to 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 toughness. It provides 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 will result in components that won’t expand or change dimensions due to contact with water.
