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

Delrin is a great plastic for turning on a lathe lathe. It is easy to turn, but it does require reduced speeds. I use this stuff to make Scottish small pipes chanters. I have ordered many items from iPlastic. The small parts always ship promptly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly durable and easily machinable, as they have very similar physical properties. They look similar, but in practical use there are a few differences that may 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 appropriate properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,as it gives an excellent finish both on manual and CNC Machines. It has a pretty 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Tecaform AH is in water applications. This environment suits acetal quite because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
