Compare and contrast Acetal Copolymer and Dupont Delrin in Round rods or sheets and plate
Dupont Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, however it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have purchased numerous items from a plastic shop in Anaheim. The smaller parts always ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have very similar physical properties. They do look the same, 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 applicable 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. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is particularly 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 aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in water applications. This environment suits acetal quite because the low moisture absorption results in components that will not expand or change dimensions due to contact with water.
