What the difference between Dupont Delrin and Acetal Copolymer in Sheet or Plate and Round Rod

Delrin is a great plastic for turning on a CNC lathe lathe. It is very easy to turn, although it does require reduced speeds. I use this plastic to make Scottish small pipes chanters. I have purchased countless items from iPlastic. Small pieces always ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are incredibly tough and easily machinable, and they have comparable physical properties. They do appear similar, but for practical use there are some differences that can make one preferable than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb 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 provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
