What the difference between Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate

Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It is pretty easy to turn, although it requires reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. Smaller pieces always ship quickly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite durable and easily machinable, and they have very comparable physical properties. They appear similar, but in practical uses there are some differences that may 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 best material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best 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 certainly 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 help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the auto industry because of its long term 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 results in components that won’t expand or alter dimensions due to contact with water.
