Acetal Sheets are of the plastics chosen within the automotive industry because of its long lasting dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water. Dupont Delrin is a great plastic for turning on a machine lathe. It’s pretty easy to turn, but it requires slow speeds. I use this material to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. The smaller parts usually ship promptly and everything is always well packed. I’ve never had a problem with an order. Between the Delrin and Acetal rods, both materials are exceptionally tough and easily machinable, and they have very comparable physical properties. They look similar, but in practical use there are some differences that may make one better POM-C Acetal Rod 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.
