Analyzing differences among Acetal Copolymer and Dupont Delrin in Sheet and Rods

Dupont Delrin is the best plastic for turning on a machine lathe. It’s pretty easy to turn, but it does require slow speeds. I use this plastic to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Small pieces usually ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly durable and easily machinable, and they have very similar physical properties. They do appear similar, but for practical uses there are some 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,as it gives an great finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal 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 many uses and is certainly 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 is one of the plastics used within the automotive industry because of its long term dimensional stability and durability. It provides 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 won’t expand or alter dimensions due to contact with water.
