Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It is very easy to turn, although it requires slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Small pieces usually ship quickly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, as they have similar physical properties. They do appear the same, but in 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, make sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an nice finish both on manual and CNC Machines. Its got 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 strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best 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 create long lasting and very durable components. Another popular area for sheet Acetal is in water applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
