Comparing Dupont Delrin and Acetal Copolymer in Round rods or sheets and plate

Homopolymer Acetal or Delrin is the perfect plastic for turning on a lathe lathe. It is pretty easy to turn, however it requires slow speeds. I’ve used this material to make Scottish small pipes chanters. I have ordered countless items from Industrial Plastic. The small parts always ship promptly and everything was well packed. I’ve never had a problem with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, as they have similar physical properties. They appear the same, but for practical uses there are a few differences that may make one better than the other. It also depends heavily on your application. As with all plastic materials, be sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is probably our best material for machining,giving an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is especially valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval along with its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the auto industry because of its long term dimensional stability and toughness. It provides 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 results in components that won’t expand or alter dimensions due to contact with water.
