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

Delrin is the perfect plastic for turning on a CNC lathe lathe. It is pretty easy to turn, however it does require reduced speeds. I’ve used this plastic to make Scottish small pipes chanters. I have ordered numerous items from Industrial Plastic. Small pieces usually ship quickly and everything has been 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, as they have very comparable physical properties. They do look similar, but in 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 definitely our best 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 critical. Acetal Sheet has the best combination of high mechanical strength, durability and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Pomalux is in water applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
