Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It is easy to turn, although it requires reduced speeds. I’ve used this plastic to make Scottish small pipes chanters. I have ordered countless items from iPlastic. The smaller pieces always ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are very tough and easily machinable, and they have very similar physical properties. They do appear the same, 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 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 definitely our primary 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 strength, 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 help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the auto industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them produce 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 results in components that will not expand or change dimensions due to contact with water.
