Analyzing differences among Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod

Delrin is a great plastic for turning on a lathe lathe. It is very easy to turn, however it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. The small pieces always 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 quite durable and easily machinable, as they have comparable physical properties. They appear similar, but in practical use there are some differences that may make one better than the other. It also depends heavily 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 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 important. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used 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 sheet Acetal 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.
