Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod
Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It’s very easy to turn, however it requires slow speeds. I use this plastic to make Scottish small pipes chanters. I have purchased numerous items from Industrial Plastic. Smaller pieces always ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, and they have comparable physical properties. They do appear similar, but for practical use there are some differences that can make one preferable 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an excellent finish both on manual and CNC Machines. Its got a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the automotive industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
