What the difference between Copolymer Acetal and Homopolymer Acetal in Sheet or Plate and Round Rod
Homopolymer Acetal or Delrin is the perfect plastic for turning on a CNC lathe lathe. It is very easy to turn, although it does require slow speeds. I use this plastic to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. Smaller parts always ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, and they have very comparable physical properties. They appear similar, but in practical use there are a few differences that may make one better 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 applicable properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,giving an nice finish both on manual and CNC Machines. Its got a very 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 outstanding 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 helped it to achieve Food & Drug Administration approval and its excellent 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 automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
