Comparing POM H and POM C acetals in Sheet and Rods

Homopolymer Acetal or Delrin is a great plastic for turning on a machine lathe. It’s pretty easy to turn, however it does require reduced speeds. I’ve used this material to make Scottish small pipes chanters. I have bought countless items from a plastic shop in Anaheim. Smaller pieces 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 incredibly durable and easily machinable, and they have comparable physical properties. They look the same, but for practical use there are some differences that can make one better than the other. It also depends 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. Its got a pretty low moisture absorption making it the ideal grade for food contact and where the dimensional stability is critical. Acetal Sheet has an ideal combination of high mechanical strength, durability and strength, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has many applications and is particularly valued 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 aid with very low friction and hard wearing food safe components.
Acetal Sheets are of the plastics used within the automotive industry because of its long term dimensional stability and durability. It offers solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in marine applications. This environment suits acetal quite because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.

The Acumullit SA technology allows the beneficial properties of the whole food botanical ingredients to be preserved and enhanced. A state-of-the art extraction process triggers the activation of the botanical compounds, so that nano-particles of the active compounds can be isolated without other substances in the plant. This causes a thinning of the cellular membranes of the fruits, herbs and seeds, and a release of the botanical components like micro and macro elements, phytonutrients, bioflavonoids, organic acids and antioxidants, making them more bioavailable. The isolated particles are forming negatively charged nano elements, creating an activated mix of highly absorbable nutrients. The activated mix of preserved and enhanced whole food plant extracts is then added to a caramel mass from which the lozenge drops are made.
