Why you may choose either Copolymer Acetal and Homopolymer Acetal in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It’s easy to turn, however it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. Smaller parts always ship promptly and everything was well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, as they have comparable physical properties. They do appear similar, but in practical use there are some differences that can make one better than the other. It also depends on your application. As with any plastic materials, make sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a very 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 strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is particularly 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 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 lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Pomalux is in water applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
