How to compare Copolymer Acetal and Homopolymer Acetal in Round rods or sheets and plate

Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It’s very easy to turn, however it requires reduced speeds. I use this material to make Scottish small pipes chanters. I have purchased countless items from iPlastic. The small parts usually ship promptly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are exceptionally durable and easily machinable, as they have very comparable physical properties. They look similar, but for practical use there are a few differences that can make one preferable than the other. It also depends on your application. As with any 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,as it gives an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the usual 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 countless applications and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb sliding abilities which aid 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 toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal well because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
