Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It is very easy to turn, but it does require slow speeds. I use this stuff to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Small pieces usually ship promptly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, and they have similar physical properties. They do look similar, but in practical use 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,as it gives an great finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred 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 applications and is particularly valued 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 help with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the auto industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in marine 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.
