Compare and contrast 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 CNC lathe lathe. It is easy to turn, although it requires slower speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. The small parts usually ship promptly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have very similar physical properties. They do look the same, but for practical uses there are a few differences that can make one preferable than the other. It also depends heavily on your application. As with all plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with 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 auto industry because of its long lasting dimensional stability and durability. It delivers 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 well because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
