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

Homopolymer Acetal or Delrin is a great plastic for turning on a lathe lathe. It’s easy to turn, although it requires slow speeds. I have used this material to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. The small pieces always ship quickly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are incredibly tough and easily machinable, as they have very similar physical properties. They look similar, but in practical uses there are a few differences that may make one preferable 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an great finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is important. Acetal Sheet has the perfect combination of high mechanical strength, durability 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 and its superb 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 auto industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
