Comparing Acetal Copolymer and Dupont Delrin in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It is simple to turn, but it does require slow speeds. I have used this material to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Small parts always ship promptly and everything was well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, as they have very comparable physical properties. They appear similar, but in practical uses there are a few 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 nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long term dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
