Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s simple to turn, however it does require slow speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Smaller pieces usually ship quickly 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 durable and easily machinable, and they have very similar physical properties. They do look similar, but for practical use 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 appropriate properties you may need for your application.
Our Acetal Sheet is probably our primary 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 perfect combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long term dimensional stability and toughness. 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 well because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
