Homopolymer Acetal or Delrin is the perfect plastic for turning on a lathe lathe. It is pretty easy to turn, but it requires slower speeds. I use this plastic to make Scottish small pipes chanters. I have purchased many items from iPlastic. The smaller parts usually ship promptly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have very similar physical properties. They appear the same, but in practical uses there are some differences that may make one better than the other. It also depends on your application. As with any 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,as it gives 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 critical. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to 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 auto 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 Sheet is in water applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
