Analyzing differences amoung Dupont Delrin and Acetal Copolymer in Sheet and Rods
Delrin is a great plastic for turning on a lathe lathe. It is pretty easy to turn, but it requires reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased many items from iPlastic. The smaller parts usually ship promptly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are exceptionally durable and easily machinable, as they have similar physical properties. They appear similar, but for practical use there are some differences that may make one better than the other. It also depends 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,as it gives an nice finish both on manual and CNC Machines. Its got 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 excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent 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 durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in moisture applications. This environment suits acetal quite because the low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
