Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Round rods or sheets and plate
Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It is simple to turn, however it does require slower speeds. I’ve used this material to make Scottish small pipes chanters. I have ordered countless items from Industrial Plastic. Small pieces always ship quickly 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 durable and easily machinable, as they have very similar physical properties. They do appear the same, but for practical uses there are a few differences that may make one better 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 probably our primary 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 preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is certainly 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 toughness. It provides 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 the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
