Dupont Delrin is the perfect plastic for turning on a machine lathe. It’s very easy to turn, however it requires reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased countless items from Industrial Plastic. The small pieces usually ship promptly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, and they have similar physical properties. They do appear similar, but in practical use there are some differences that can make one better than the other. It also depends on your application. As with any plastic materials, be 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 pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is particularly of value 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 aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
