What the difference between 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 machine lathe. It is very easy to turn, however it does require slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have bought countless items from iPlastic. Small parts usually ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly durable and easily machinable, as they have comparable physical properties. They look the same, but in practical uses there are some 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,as it gives an excellent 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 important. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous 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 and its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics chosen within the auto industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
