What the difference between Dupont Delrin and Acetal Copolymer in Sheet and Rods
Delrin is the best plastic for turning on a lathe lathe. It is pretty easy to turn, but it does require reduced speeds. I use this material to make Scottish small pipes chanters. I have bought numerous items from a plastic shop in Anaheim. Small parts always ship quickly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, and they have very similar physical properties. They do look similar, but for practical uses there are a few differences that can make one preferable than the other. It also depends on your application. As with all plastic materials, make sure to check the typical properties data sheet for the appropriate 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 ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help 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 lasting dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in boating applications. This environment suits acetal quite because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
