Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods
Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is very easy to turn, but it does require slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought many items from a plastic shop in Anaheim. Small parts always ship quickly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, as they have comparable physical properties. They appear similar, but for practical use there are a few differences that may make one preferable than the other. It also depends on your application. As with any 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 definitely our choice material for machining,as it gives an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal 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 of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the auto industry because of its long term dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Sustarin C 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.
