Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Round rods or sheets and plate
Delrin is the perfect plastic for turning on a machine lathe. It is easy to turn, but it requires slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. Smaller parts always ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite durable and easily machinable, as they have very similar physical properties. They do look the same, but in practical use there are some differences that can make one better than the other. It also depends on your application. As with any plastic materials, be sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an great finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in water applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
