Comparing Acetal Copolymer and Dupont Delrin in Round rods or sheets and plate

Homopolymer Acetal or Delrin is the perfect plastic for turning on a CNC lathe lathe. It is easy to turn, but it requires slow speeds. I use this material to make Scottish small pipes chanters. I have purchased numerous items from Industrial Plastic. The small parts usually ship quickly and everything is always well packed. I have never had an issue with an order.
Between the Delrin and POM-C rods, both materials are very tough and easily machinable, as they have comparable physical properties. They do look similar, but in practical use there are some differences that may make one preferable than the other. It also depends heavily 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 probably our choice material for machining,as it gives an excellent finish both on manual and CNC Machines. It has a very low moisture absorption making it the ideal grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, 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 along with its excellent sliding abilities which help with very low friction and hard wearing food safe components.
Acetal Sheet is one of the plastics used within the automotive industry because of its long lasting dimensional stability and toughness. It provides solutions for designers to help them produce long lasting and very durable components. Another popular area for Acetal Sheet is in water applications. This environment suits acetal well because its low moisture absorption will result in components that won’t 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.
