Looking at comparisons between Copolymer Acetal and Homopolymer Acetal in Sheet or Plate and Round Rod

Reasons Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s easy to turn, but it requires slower speeds. I use this material to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Smaller pieces usually ship promptly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, and they have very comparable physical properties. They look the same, but in practical use 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its excellent sliding abilities which help 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 lasting dimensional stability and toughness. It provides 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 quite because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
