Why you may choose either Acetal Copolymer and Dupont Delrin in Sheet or Plate and Round Rod. https://iplasticsupply.com/home/plastic-materials-list/acetal-delrin-celcon-basf-pom-pomalux-sheet-rod/ http://ips-delrin.com/

Delrin is the best plastic for turning on a machine lathe. It is really quite pretty easy to turn, but it requires reduced speeds. We regularly use this plastic to make Scottish small pipes chanters. I have purchased numerous items from a plastic shop in Anaheim. Small pieces usually ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are incredibly tough and easily machinable, as they have comparable physical properties. They look the same, but for practical use there are a few 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 applicable properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,as it gives an excellent 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 important. Acetal Sheet has the perfect combination of high mechanical strength, durability and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications 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 superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the plastics chosen within the automotive industry because of its long lasting dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal well because its low moisture absorption results in components that simply will not expand or alter dimensions due to contact with water.
