Looking at comparisons between Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Top reasons Dupont Delrin Homopolymer is a great plastic for turning on a lathe lathe. It is easy to turn, however it does require reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have bought numerous items from Industrial Plastic. The smaller pieces always ship quickly and everything was well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly durable and easily machinable, and they have similar physical properties. They look similar, but for practical use there are a few differences that can make one better 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 definitely our best material for machining,giving an nice 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 strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications 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 help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics chosen within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them create 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.
