Looking at comparisons between Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Delving into main reason Dupont Delrin is a great plastic for turning on a machine lathe. It’s very easy to turn, although it does require slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. The small pieces always ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, and they have comparable physical properties. They look the same, but for practical use there are some differences that may make one better than the other. It also depends on your application. As with any plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is probably our choice 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 important. 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 many applications and is certainly valued 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 help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
