How to compare Acetal Copolymer and Dupont Delrin in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is easy to turn, although it requires reduced speeds. I use this plastic to make Scottish small pipes chanters. I have bought numerous items from Industrial Plastic. Small parts always ship promptly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, and they have very comparable physical properties. They do appear the same, but for practical uses there are some differences that can make one preferable than the other. It also depends heavily on your application. As with any 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 probably our choice material for machining,giving an nice 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 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 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 help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics used within the auto industry because of its long term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in water applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
