Analyzing differences amoung Copolymer Acetal and Dupont Delrin Homopolymer in Round rods or sheets and plate
Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is pretty easy to turn, however it does require reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased many items from Industrial Plastic. The smaller pieces always ship promptly and everything was well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, and they have very similar physical properties. They do look similar, but in practical uses there are a few differences that can make one better than the other. It also depends on your application. As with any plastic materials, make sure to check the typical properties data sheet for the desired properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the preferred 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 numerous uses and is particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which aid 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 delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in water applications. This environment suits acetal quite because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
