What the difference between Copolymer Acetal and Homopolymer Acetal in Sheet and Rods
Homopolymer Acetal or Delrin is the perfect plastic for turning on a CNC lathe lathe. It’s very easy to turn, however it requires slower speeds. I use this stuff to make Scottish small pipes chanters. I have ordered numerous items from a plastic shop in Anaheim. The small parts usually ship quickly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are incredibly tough and easily machinable, and they have comparable physical properties. They look the same, but in practical use there are some differences that may make one preferable than the other. It also depends on your application. As with all 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 probably our primary material for machining,as it gives an great finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless 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 superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and toughness. 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 results in components that won’t expand or change dimensions due to contact with water.
