What the difference between Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It is pretty easy to turn, but it does require reduced speeds. I’ve used this plastic to make Scottish small pipes chanters. I have purchased numerous items from a plastic shop in Anaheim. Small pieces always ship quickly and everything is always well packed. I have 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 comparable physical properties. They appear the same, but for practical uses there are a few differences that may make one preferable than the other. It also depends heavily on your application. As with all 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 probably our primary material for machining,giving 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 toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is especially of value in the food preparation industry. Because of its low moisture absorption it gained 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 is one of the engineering 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 Pomalux is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
