How to compare Dupont Delrin and Acetal Copolymer in Sheet and Rods
Delrin is the perfect plastic for turning on a machine lathe. It is very easy to turn, but it does require slower speeds. I have used this material to make Scottish small pipes chanters. I have bought countless items from iPlastic. Smaller pieces always ship quickly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, as they have comparable physical properties. They appear similar, but for practical use there are some differences that can make one preferable 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our choice material for machining,as it gives an great 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 important. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is especially of value 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 help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best 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 sheet 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.
