Compare and contrast POM H and POM C acetals in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a CNC lathe lathe. It is simple to turn, however it does require slow speeds. I use this stuff to make Scottish small pipes chanters. I have purchased numerous items from iPlastic. Smaller pieces usually ship promptly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are quite tough and easily machinable, and they have comparable physical properties. They appear similar, but in practical use there are a few differences that can make one better than the other. It also depends heavily on your application. As with all plastic materials, be 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,as it gives an great 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 superb sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless applications and is especially of value in the food preparation industry. Because of its low moisture absorption it gained Food & Drug Administration approval and its superb sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the engineering plastics chosen within the automotive industry because of its long term dimensional stability and toughness. It delivers solutions for designers to help them create long lasting and very durable components. Another popular area for Tecaform AH is in marine applications. This environment suits acetal quite because its low moisture absorption results in components that won’t expand or alter dimensions due to contact with water.
