What the difference between Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod
Delrin is a great plastic for turning on a CNC lathe lathe. It’s very easy to turn, but it requires slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. The smaller parts always ship quickly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, and they have very comparable physical properties. They do appear similar, but for practical use there are a few differences that can make one preferable 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,giving an excellent 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 the best combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in moisture applications. This environment suits acetal quite because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
