Compare and contrast Copolymer Acetal and Homopolymer Acetal in Sheet or Plate and Round Rod

Delrin is the best plastic for turning on a machine lathe. It’s easy to turn, however it requires slower speeds. I use this material to make Scottish small pipes chanters. I have purchased many items from iPlastic. The smaller parts usually ship quickly and everything is always 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 very similar physical properties. They appear the same, but in practical use there are a few differences that can make one better 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,giving an great 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 critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses 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 excellent 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 auto 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 Acetal is in water applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
