Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Homopolymer Acetal or Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s very easy to turn, however it does require slow speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased numerous items from Industrial Plastic. Smaller pieces usually ship promptly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are incredibly durable and easily machinable, and they have very similar physical properties. They do appear similar, but for practical use there are some differences that may make one preferable 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 great finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen 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 Pomalux is in boating applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
