Comparing Acetal Copolymer and Dupont Delrin in Round rods or sheets and plate

Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is pretty easy to turn, but it does require slower speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. Smaller pieces always ship quickly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, and they have very similar physical properties. They do appear the same, but for practical uses there are some 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to 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 is in water applications. This environment suits acetal quite because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
