What the difference between Acetal Copolymer and Dupont Delrin in Sheet and Rods

Homopolymer Acetal or Delrin is the perfect plastic for turning on a lathe lathe. It’s simple to turn, although it requires slow speeds. I use this material to make Scottish small pipes chanters. I have purchased many items from iPlastic. Small parts always ship promptly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, as they have comparable physical properties. They appear the same, but for practical use there are a few differences that can make one better 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 definitely our primary material for machining,as it gives an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is especially 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 chosen within the automotive industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Tecaform AH is in water applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
