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

Dupont Delrin is a great plastic for turning on a CNC lathe lathe. It’s very easy to turn, although it does require reduced speeds. I use this material to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. The small parts always ship quickly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, as they have very similar physical properties. They look similar, but in practical uses 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, be sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is probably 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 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 numerous applications and is certainly 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 aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in marine applications. This environment suits acetal well because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
