Professionals compare Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod
Reasons Dupont Delrin Homopolymer is a great plastic for turning on a machine lathe. It is very easy to turn, although it requires slower speeds. I use this stuff to make Scottish small pipes chanters. I have ordered many items from a plastic shop in Anaheim. Smaller pieces always ship quickly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, and they have very similar physical properties. They look the same, but for practical uses there are a few differences that may make one better 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 best 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, hardness and strength, 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 helped it to achieve Food & Drug Administration approval along with its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics chosen within the automotive industry because of its long lasting dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
