Homopolymer Acetal or Delrin is the perfect plastic for turning on a lathe lathe. It’s pretty easy to turn, but it requires reduced speeds. I have used this plastic to make Scottish small pipes chanters. I have ordered numerous items from a plastic shop in Anaheim. Small parts usually ship quickly and everything is always well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have very similar physical properties. They appear the same, but for practical uses there are a few differences that may make one preferable than the other. It also depends on your application. As with all plastic materials, make sure to check the typical properties data sheet for the appropriate properties you may need for your application.
Our Acetal Sheet is definitely our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. 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 many uses and is particularly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics chosen within the automotive industry because of its long term dimensional stability and durability. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Acetal is in moisture 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.
