Comparing Copolymer Acetal and Homopolymer Acetal in Sheet and Rods
Delrin is the perfect plastic for turning on a machine lathe. It’s very easy to turn, but it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Small pieces usually ship promptly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, and they have comparable physical properties. They look the same, but in practical use there are some differences that can make one better than the other. It also depends on your application. As with all plastic materials, be 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 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 important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially 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 used within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in water applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
