What the difference between Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod

Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is pretty easy to turn, but it does require slow speeds. I have used this plastic to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. The small pieces usually ship promptly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, and they have very comparable physical properties. They do look similar, but for practical use there are a few differences that can make one preferable 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,as it gives 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 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 many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the auto industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in boating 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.
