Comparing Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate

Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It is simple to turn, although it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. Smaller parts usually ship quickly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have comparable physical properties. They do look the same, but for practical uses there are some differences that may make one better than the other. It also depends 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 choice material for machining,as it gives an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics chosen within the automotive industry because of its long term 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 quite because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
