Analyzing differences amoung Acetal Copolymer and Dupont Delrin in Sheet and Rods

Delrin is a great plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, although it requires reduced speeds. I have used this stuff to make Scottish small pipes chanters. I have bought many items from iPlastic. The small pieces 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 durable and easily machinable, and they have comparable physical properties. They appear similar, but in practical use there are some differences that may 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 definitely our primary material for machining,as it gives an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is especially valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the auto 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 Sustarin C is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
