What the difference between POM H and POM C acetals in Sheet and Rods
Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, but it does require reduced speeds. I use this plastic to make Scottish small pipes chanters. I have ordered many items from iPlastic. Small pieces usually ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have comparable physical properties. They do look similar, but for practical use there are some differences that can 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 choice material for machining,giving an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and 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 used within the automotive industry because of its long lasting dimensional stability and toughness. It offers 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 its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
