Compare and contrast Copolymer Acetal or Dupont Delrin in Sheet and Rods

Dupont Delrin is a great plastic for turning on a machine lathe. It’s easy to turn, but it requires slow speeds. I use this stuff to make Scottish small pipes chanters. I have ordered countless items from a plastic shop in Anaheim. Smaller parts usually ship quickly and everything was 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 comparable physical properties. They do look similar, but for practical use there are some differences that can make one better than the other. It also depends heavily 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 probably our best material for machining,as it gives an excellent finish both on manual and CNC Machines. Its got a very low moisture absorption making it the usual 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 excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its superb sliding abilities which help 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 lasting dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in water applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
