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

Dupont Delrin is a great plastic for turning on a CNC lathe lathe. It is simple to turn, however it does require slow speeds. I have used this stuff to make Scottish small pipes chanters. I have bought countless items from Industrial Plastic. The smaller parts usually ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, and they have comparable physical properties. They appear the same, but in practical use there are a few differences that can make one better 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,as it gives an nice 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 perfect combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the auto 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 moisture applications. This environment suits acetal well because the low moisture absorption results in components that will not expand or change dimensions due to contact with water.
