Comparing Acetal Copolymer and Dupont Delrin in Sheet and Rods
Delrin is the best plastic for turning on a machine lathe. It’s simple to turn, however it requires reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have bought countless items from iPlastic. The smaller parts always ship quickly and everything has been well packed. I have 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 similar physical properties. They do appear similar, but in practical use there are a few differences that may make one preferable 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 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 critical. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics used within the auto industry because of its long term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
