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

Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, but it does require slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have purchased many items from a plastic shop in Anaheim. The smaller pieces usually ship quickly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, as they have similar physical properties. They do look similar, but in 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, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an excellent finish both on manual and CNC Machines. Its got a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is certainly 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 Sheet stock, perhaps the best of the plastics chosen within the auto industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
