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

Homopolymer Acetal or Delrin is the perfect plastic for turning on a CNC lathe lathe. It is simple to turn, although it does require reduced speeds. I use this stuff to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. The smaller parts usually ship promptly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have comparable physical properties. They appear similar, but for practical use there are a few differences that can make one better 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 applicable properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,as it gives an great 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, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics chosen within the auto industry because of its long term dimensional stability and toughness. It offers 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 results in components that will not expand or change dimensions due to contact with water.
