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

Delrin is the perfect plastic for turning on a machine lathe. It’s pretty easy to turn, although it does require reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Smaller parts usually ship quickly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, as they have very comparable physical properties. They do appear the same, but in practical uses there are some differences that may make one preferable 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 desired properties you may need for your application.
Our Acetal Sheet is probably our choice material for machining,as it gives an great finish both on manual and CNC Machines. It has a pretty 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 outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics used within the auto 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 Sheet is in moisture applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
