Reasons to choose Copolymer Acetal and Homopolymer Acetal in Sheet and Rods
Homopolymer Acetal or Delrin is the perfect plastic for turning on a machine lathe. It is easy to turn, however it requires slower speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought many items from iPlastic. The smaller parts usually 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 exceptionally tough and easily machinable, and they have similar physical properties. They do appear similar, but in practical use there are a few differences that can 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 desired properties you may need for your application.
Our Acetal Sheet is probably 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, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the automotive industry because of its long term dimensional stability and toughness. 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 alter dimensions due to contact with water.
