Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It’s pretty easy to turn, however it requires slow speeds. I have used this plastic to make Scottish small pipes chanters. I have bought numerous items from a plastic shop in Anaheim. The smaller pieces usually ship promptly 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 tough and easily machinable, as they have very similar physical properties. They do appear the same, but for practical uses there are a few differences that can make one preferable than the other. It also depends heavily 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 choice material for machining,as it gives an nice 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 countless uses and is certainly of value 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 stock, perhaps the best of the plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in moisture 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.
