What the difference between POM H and POM C acetals in Sheet or Plate and Round Rod

Dupont Delrin is a great plastic for turning on a machine lathe. It is very easy to turn, however it does require slow speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased numerous items from a plastic shop in Anaheim. The smaller pieces always ship promptly and everything is always well packed. I have never had a problem with an order.
Between the Delrin and POM-C rods, both materials are incredibly durable and easily machinable, as they have similar physical properties. They look the same, but in practical uses there are some 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 desired properties you may need for your application.
Our Acetal Sheet is definitely our best material for machining,giving an nice finish both on manual and CNC Machines. It has a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has an ideal combination of high mechanical strength, durability and toughness, giving it excellent sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is especially valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval and 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 used within the auto industry because of its long lasting 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 well because its low moisture absorption results in components that won’t expand or change dimensions due to contact with water.
