Homopolymer Acetal or Delrin is the best plastic for turning on a lathe lathe. It is easy to turn, however it requires slower speeds. I use this stuff to make Scottish small pipes chanters. I have ordered numerous items from iPlastic. Smaller pieces always ship quickly 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 very durable and easily machinable, and they have comparable physical properties. They appear 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 any plastic materials, be 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,giving 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, hardness and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous 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 excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the automotive 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 Pomalux is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that won’t expand or change dimensions due to contact with water.
