Compare and contrast Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod
Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, but it does require slow speeds. I have used this stuff to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. The small parts always ship promptly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, and they have very comparable physical properties. They appear similar, but for practical use 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, make 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,giving an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal 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 excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in boating applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
