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

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is easy to turn, although it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. Small parts always ship quickly and everything was 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 similar physical properties. They appear the same, but for practical use there are a few differences that can make one preferable than the other. It also depends heavily on your application. As with any 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 best material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very 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 strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is especially valued 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 is one of the plastics chosen within the auto industry because of its long lasting dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal well because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
