Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is easy to turn, although it requires reduced speeds. I have used this material to make Scottish small pipes chanters. I have ordered countless items from Industrial Plastic. Small pieces always ship promptly and everything has been well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are exceptionally durable and easily machinable, as they have similar physical properties. They appear 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 all 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 definitely our primary material for machining,giving an nice 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 best 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 particularly of value in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and its excellent sliding abilities which aid with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics used within the automotive industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Sustarin C is in boating applications. This environment suits acetal quite because its low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
