What the difference between 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’s easy to turn, but it does require reduced speeds. I’ve used this stuff to make Scottish small pipes chanters. I have bought numerous items from a plastic shop in Anaheim. The small pieces always ship quickly and everything was well packed. I have 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 do appear the same, but in practical use there are a few differences that may make one preferable than the other. It also depends 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 probably our choice material for machining,giving 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 important. Acetal Sheet has the perfect combination of high mechanical strength, hardness and toughness, giving it outstanding 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 along with its excellent sliding abilities which help 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 delivers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in marine applications. This environment suits acetal well because the low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
