Professionals compare Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod

Important reasons Dupont Delrin is the best plastic for turning on a machine lathe. It is very easy to turn, although it does require reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. Smaller pieces always ship quickly and everything is always 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 similar physical properties. They appear the same, but for practical uses there are a few differences that can 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our choice 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 usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It offers 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 quite because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
