Analyzing differences amoung Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod

Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It’s easy to turn, however it does require slower speeds. I’ve used this stuff to make Scottish small pipes chanters. I have ordered countless items from a plastic shop in Anaheim. Small parts always ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, as they have similar physical properties. They do look the same, but in practical uses there are some differences that can make one better than the other. It also depends heavily on your application. As with all plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an excellent 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 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 certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics used within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in boating 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.
