Comparing Copolymer Acetal and Dupont Delrin Homopolymer in Sheet or Plate and Round Rod
Homopolymer Acetal or Delrin is the perfect plastic for turning on a lathe lathe. It is easy to turn, however it requires reduced speeds. I use this stuff to make Scottish small pipes chanters. I have purchased countless items from a plastic shop in Anaheim. Small parts always ship quickly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are quite durable and easily machinable, as they have very comparable physical properties. They look the same, but in practical use there are some differences that can make one preferable than the other. It also depends on your application. As with any 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 probably our primary material for machining,as it gives an nice finish both on manual and CNC Machines. Its got a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is critical. Acetal Sheet has the perfect combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous 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 in addition to its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics chosen within the auto industry because of its long term dimensional stability and durability. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Sustarin C is in marine applications. This environment suits acetal well because its low moisture absorption will result in components that will not expand or alter dimensions due to contact with water.
