Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, although it does require slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought numerous items from a plastic shop in Anaheim. The smaller pieces always ship promptly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are exceptionally durable and easily machinable, as they have very similar physical properties. They do appear similar, but in practical uses there are a few 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 desired properties you may need for your application.
Our Acetal Sheet is probably our primary 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 the best combination of high mechanical strength, hardness and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is particularly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the automotive industry because of its long term dimensional stability and durability. It provides 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 quite because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
