What the difference between Copolymer Acetal and Homopolymer Acetal in Round rods or sheets and plate
Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, but it requires slower speeds. I’ve used this material to make Scottish small pipes chanters. I have bought many items from Industrial Plastic. Smaller parts always ship quickly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, and they have comparable physical properties. They do appear the same, but for practical uses there are a few differences that can make one better than the other. It also depends on your application. As with all 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 choice material for machining,giving an excellent finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and 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 term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in marine applications. This environment suits acetal quite because its low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
