What the difference between 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 pretty easy to turn, however it requires slower speeds. I have used this material to make Scottish small pipes chanters. I have bought countless items from Industrial Plastic. The smaller pieces usually ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, and they have very similar physical properties. They look similar, 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, make sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got 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 superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous 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 excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
