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

Delrin is a great plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, although it requires slower speeds. I’ve used this plastic to make Scottish small pipes chanters. I have ordered many items from Industrial Plastic. The small parts always ship promptly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have comparable physical properties. They look the same, but in practical uses there are a few differences that can make one preferable than the other. It also depends heavily on your application. As with any 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 probably our primary material for machining,giving an excellent finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect 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 certainly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and 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 automotive industry because of its long lasting dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
