Analyzing differences amoung Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Homopolymer Acetal or Delrin is the perfect plastic for turning on a lathe lathe. It’s pretty easy to turn, however it does require slower speeds. I use this plastic to make Scottish small pipes chanters. I have purchased countless items from iPlastic. Small pieces usually ship quickly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, as they have very comparable physical properties. They appear the same, but in practical use there are a few differences that can make one preferable 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 choice material for machining,giving an excellent finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, durability and strength, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb 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 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 Sheet is in boating applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
