Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It’s simple to turn, however it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought numerous items from Industrial Plastic. Small parts usually ship quickly and everything has been well packed. I’ve 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 comparable physical properties. They appear similar, but in practical uses there are some differences that may make one better than the other. It also depends 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 probably our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got 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, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses 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 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 lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
