How to compare POM H and POM C acetals in Sheet and Rods
Homopolymer Acetal or Delrin is the best plastic for turning on a machine lathe. It’s pretty easy to turn, although it does require slower speeds. I use this stuff to make Scottish small pipes chanters. I have bought numerous items from Industrial Plastic. The smaller pieces always ship quickly and everything is always well packed. I’ve never had an issue with an order.
Between the Delrin and Acetal rods, both materials are very durable and easily machinable, and they have comparable physical properties. They do look similar, but in practical uses 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 applicable 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. Its got a pretty low moisture absorption making it the usual grade for food contact and where the dimensional stability is critical. Acetal Sheet has the best combination of high mechanical strength, hardness 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 gained Food & Drug Administration approval along with its excellent sliding abilities which aid 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 lasting dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for sheet Acetal is in water applications. This environment suits acetal quite because its low moisture absorption results in components that will not expand or change dimensions due to contact with water.
