Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod
Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s simple to turn, however it requires slower speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased many items from iPlastic. The small pieces usually ship quickly and everything was well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, and they have very comparable physical properties. They do appear similar, but for practical uses there are some differences that may make one better than the other. It also depends 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 choice material for machining,giving an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is certainly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the auto industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Tecaform AH is in moisture applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
