Compare and contrast Copolymer Acetal and Dupont Delrin Homopolymer in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is very easy to turn, however it requires slow speeds. I’ve used this plastic to make Scottish small pipes chanters. I have bought many items from a plastic shop in Anaheim. Smaller parts always ship quickly and everything has been well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are very durable and easily machinable, and they have similar physical properties. They do appear similar, but for practical use there are some differences that can make one preferable 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 primary material for machining,as it gives an excellent finish both on manual and CNC Machines. Its got a very 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, hardness and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially 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 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 lasting dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in boating applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
