Comparing Dupont Delrin and Acetal Copolymer in Sheet and Rods

Homopolymer Acetal or Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s easy to turn, however it requires slow speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Small pieces always ship promptly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, and they have comparable physical properties. They appear the same, but in practical uses there are some differences that can make one preferable 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 appropriate properties you may need for your application.
Our Acetal Sheet is probably our choice 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 critical. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in water applications. This environment suits acetal quite because the low moisture absorption results in components that will not expand or change dimensions due to contact with water.
