Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is easy to turn, however it requires slower speeds. I use this material to make Scottish small pipes chanters. I have bought many items from iPlastic. The small pieces always ship quickly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, as they have very comparable physical properties. They do appear the same, but for practical uses there are some differences that may make one better 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 probably our choice material for machining,as it gives an great 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 critical. 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 countless 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 excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in moisture applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
