Reasons to choose Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Dupont Delrin is the best plastic for turning on a machine lathe. It is simple to turn, but it does require slow speeds. I’ve used this material to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Small pieces usually ship quickly and everything has been 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 very comparable physical properties. They do look similar, but for practical uses there are a few differences that can make one preferable than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,giving 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, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
