Analyzing differences amoung Copolymer Acetal and Homopolymer Acetal in Sheet or Plate and Round Rod

Delrin is a great plastic for turning on a CNC lathe lathe. It is pretty easy to turn, however it does require slow speeds. I’ve used this material to make Scottish small pipes chanters. I have bought many 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 exceptionally tough and easily machinable, and they have very similar physical properties. They do look similar, but in practical use there are a few differences that may make one better than the other. It also depends heavily 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 probably our best material for machining,as it gives an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the best 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 superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet stock, perhaps the best of the engineering plastics chosen within the auto industry because of its long term dimensional stability and toughness. It provides solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in moisture applications. This environment suits acetal quite because the low moisture absorption will result in components that won’t expand or alter dimensions due to contact with water.
