Comparing Acetal Copolymer and Dupont Delrin in Sheet and Rods

Dupont Delrin is a great plastic for turning on a machine lathe. It’s very easy to turn, although it requires slow speeds. I have used this material to make Scottish small pipes chanters. I have ordered many items from Industrial Plastic. The small parts usually 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 incredibly durable and easily machinable, as they have similar physical properties. They do look similar, but in practical use there are a few 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 best material for machining,giving an nice finish both on manual and CNC Machines. It has a very low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics chosen within the automotive industry because of its long term dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for Tecaform AH is in moisture applications. This environment suits acetal well because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
