Comparing Dupont Delrin and Acetal Copolymer in Sheet and Rods
Delrin is a great plastic for turning on a lathe lathe. It is easy to turn, however it requires slower speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. The smaller pieces always ship quickly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, and they have similar physical properties. They look the same, but for practical use there are a few differences that can make one preferable than the other. It also depends on your application. As with all plastic materials, make sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a very 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 strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications 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 aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics chosen within the auto industry because of its long term dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in marine 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.
