Analyzing differences amoung Copolymer Acetal and Homopolymer Acetal in Round rods or sheets and plate
Homopolymer Acetal or Delrin is the best plastic for turning on a CNC lathe lathe. It’s very easy to turn, however it requires reduced speeds. I have used this material to make Scottish small pipes chanters. I have ordered numerous items from Industrial Plastic. Smaller parts usually ship promptly and everything has been well packed. I’ve never had a problem with an order.
Between the Delrin and Acetal rods, both materials are very tough and easily machinable, and they have comparable physical properties. They do look similar, but for 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, 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 best material for machining,as it gives an nice finish both on manual and CNC Machines. It has 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, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has numerous applications and is especially valued in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval along with its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheets are of the engineering plastics used within the automotive industry because of its long term dimensional stability and durability. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal is in water applications. This environment suits acetal quite because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
