What the difference between Dupont Delrin and Acetal Copolymer in Sheet and Rods

Dupont Delrin is the best plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, although it does require slow speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought numerous items from iPlastic. Smaller pieces usually ship promptly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, as they have comparable physical properties. They do look the same, but for practical uses there are a few 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 appropriate properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,as it gives an great 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 critical. Acetal Sheet has the perfect combination of high mechanical strength, hardness and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics used within the automotive industry because of its long lasting dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Tecaform AH is in marine 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.
