What the difference between Acetal Copolymer and Dupont Delrin in Round rods or sheets and plate
Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is pretty easy to turn, although it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Small parts usually ship quickly and everything was well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite durable and easily machinable, and they have very comparable physical properties. They appear similar, but for practical use there are a few 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 appropriate properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,giving an great finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, durability and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous 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 help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal well because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
