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

Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, however it does require slow speeds. I’ve used this material to make Scottish small pipes chanters. I have bought many items from Industrial Plastic. The smaller parts usually ship promptly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, and they have very similar physical properties. They do appear similar, but in practical use there are a few differences that can make one better than the other. It also depends heavily on your application. As with all 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 best 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 preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless 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 in addition to its excellent sliding abilities which help 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 lasting dimensional stability and toughness. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in moisture applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
