What the difference between Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s easy to turn, however it does require slow speeds. I use this material to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. Smaller pieces always ship promptly and everything was well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have comparable physical properties. They look similar, 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, be 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. It has a pretty low moisture absorption making it the ideal 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 superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is certainly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with 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 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 Tecaform AH is in water applications. This environment suits acetal well because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
