Compare and contrast Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods
Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It’s very easy to turn, however it does require slow speeds. I use this material to make Scottish small pipes chanters. I have ordered many items from iPlastic. Smaller pieces always ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, as they have very similar physical properties. They appear similar, but in practical use there are some differences that may 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,as it gives an excellent finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications 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 in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in boating applications. This environment suits acetal well because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
