Comparing Copolymer Acetal and Homopolymer Acetal in Round rods or sheets and plate
Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It’s easy to turn, although it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have ordered countless items from iPlastic. The small parts usually ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, as they have similar physical properties. They appear similar, but for practical use there are some differences that can make one preferable than the other. It also depends heavily 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 definitely our choice material for machining,as it gives an great 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, hardness and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is certainly valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the automotive industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
