What the difference between Dupont Delrin and Acetal Copolymer in Sheet and Rods
Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s pretty easy to turn, but it requires slow speeds. I have used this material to make Scottish small pipes chanters. I have purchased numerous items from Industrial Plastic. Smaller parts usually ship promptly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are quite tough and easily machinable, and they have very comparable physical properties. They do look the same, but for practical use there are a few differences that can make one preferable 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 applicable properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,giving an excellent finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, durability and strength, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many uses and is certainly of value 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 aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long lasting dimensional stability and durability. It delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in water applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or alter dimensions due to contact with water.
