Looking at comparisons between Dupont Delrin and Acetal Copolymer in Sheet and Rods

Why Dupont Delrin 150SA is the perfect plastic for turning on a machine lathe. It is simple to turn, but it does require reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have purchased numerous items from a plastic shop in Anaheim. The small pieces always ship quickly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and POM-C rods, both materials are incredibly tough and easily machinable, and they have very similar physical properties. They do look the same, but in practical use there are some differences that can make one better than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,as it gives an excellent 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 excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous uses and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval in addition to its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the auto industry because of its long term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in marine applications. This environment suits acetal quite because its low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
