What the difference between Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s very easy to turn, although it requires slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased countless items from iPlastic. The smaller parts usually ship promptly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, as they have very comparable physical properties. They do look the same, but for practical use there are some differences that may make one preferable than the other. It also depends on your application. As with all 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 definitely our best material for machining,giving an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained 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 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 sheet Acetal is in marine applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
