What the difference between Dupont Delrin and Acetal Copolymer in Sheet and Rods
Delrin is a great plastic for turning on a lathe lathe. It is easy to turn, but it requires slow speeds. I have used this stuff to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. The small parts always ship promptly and everything was well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, and they have similar physical properties. They do appear the same, but in practical uses 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 appropriate properties you may need for your application.
Our Acetal Sheet is probably 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, hardness and strength, 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 gained Food & Drug Administration approval along with its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for sheet Acetal is in moisture applications. This environment suits acetal well because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
