Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Delrin is a great plastic for turning on a lathe lathe. It’s pretty easy to turn, but it does require reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have ordered many items from Industrial Plastic. The smaller parts always ship quickly and everything was 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 similar physical properties. They appear similar, but in practical use there are some differences that may 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 applicable properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,giving an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, durability 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 helped it to achieve Food & Drug Administration approval along with 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 delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal well because its low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
