How to choose Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod

Why Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is easy to turn, but it does require slow speeds. I have used this material to make Scottish small pipes chanters. I have ordered countless items from Industrial Plastic. The smaller pieces usually ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, and they have comparable physical properties. They look similar, but in practical use there are some differences that may 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,as it gives an great 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 best combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly 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 aid 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 durability. It offers solutions for designers to help them produce 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 won’t expand or alter dimensions due to contact with water.
