Comparing Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod
Dupont Delrin is the perfect plastic for turning on a lathe lathe. It’s simple to turn, although it does require slower speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased numerous items from a plastic shop in Anaheim. The smaller pieces always ship quickly and everything was well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, as they have similar physical properties. They do appear the same, but for practical uses there are some differences that may make one preferable 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 excellent 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 important. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent 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 provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in marine 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.
