What the difference between Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate

Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s pretty easy to turn, but it requires reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have ordered countless items from Industrial Plastic. Small parts usually ship promptly and everything was well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, and they have very comparable physical properties. They appear the same, but for practical uses there are some differences that may make one preferable than the other. It also depends on your application. As with any plastic materials, be sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,as it gives an excellent finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is especially of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
