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

Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It’s pretty easy to turn, however it requires slow speeds. I use this stuff to make Scottish small pipes chanters. I have purchased numerous items from Industrial Plastic. Smaller parts usually ship quickly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have very similar physical properties. They appear similar, but for practical use there are a few 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 definitely our primary material for machining,as it gives 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 critical. 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 many applications and is especially valued 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 Sheet is one of the engineering plastics chosen within the auto industry because of its long lasting dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in boating applications. This environment suits acetal well because its low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
