Comparing Dupont Delrin and Acetal Copolymer in Sheet or Plate and Round Rod

Homopolymer Acetal or Delrin is the best plastic for turning on a lathe lathe. It’s very easy to turn, however it does require reduced speeds. I’ve used this plastic to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. Small parts always ship promptly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, as they have comparable physical properties. They do appear the same, but for practical uses there are a few differences that can 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an great finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, hardness and strength, giving it superb 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 helped it to achieve Food & Drug Administration approval along with its excellent 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 lasting dimensional stability and toughness. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in water applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
