Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It is easy to turn, although it does require slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Smaller parts always ship quickly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, and they have similar physical properties. They do appear the same, but for practical uses there are some differences that may make one preferable than the other. It also depends heavily on your application. As with all plastic materials, be sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,giving an great finish both on manual and CNC Machines. Its got 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 strength, giving it superb 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 and its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the automotive 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 Acetal Sheet is in marine 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.
