Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, although it requires slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. Small pieces always ship promptly 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 quite tough and easily machinable, as they have very comparable physical properties. They look similar, but for practical uses there are a few differences that can make one better 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is especially 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 excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics used within the auto industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
