Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, but it requires reduced speeds. I use this material to make Scottish small pipes chanters. I have bought numerous items from iPlastic. The smaller pieces usually ship promptly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly durable and easily machinable, as they have comparable physical properties. They do appear 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 any 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 choice material for machining,as it gives an nice 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 important. Acetal Sheet has the best combination of high mechanical strength, hardness 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 help with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in marine applications. This environment suits acetal well because its low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
