Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s pretty easy to turn, although it does require slow speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased countless items from iPlastic. Smaller parts always ship quickly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are exceptionally tough and easily machinable, and they have similar physical properties. They look the same, but for practical use there are a few differences that may make one preferable than the other. It also depends 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 probably our primary material for machining,as it gives an excellent 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, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the auto industry because of its long lasting dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in water 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.
