Analyzing differences among Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod

Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It’s pretty easy to turn, but it does require reduced speeds. I have used this material to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. Small pieces usually ship quickly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, and they have very similar physical properties. They do appear similar, but in practical use there are a few differences that can 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 best material for machining,giving an great finish both on manual and CNC Machines. It has a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and 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 used within the automotive industry because of its long lasting dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in marine applications. This environment suits acetal quite because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
