grinding of polymers


Posted on January 23, 2019



What is the easiest way to grind polymer pellets into powder?The key is to do the grinding below the glass temperature of the polymer to convert it into a powder - as you mention, if material heats on grinding it can make it more difficult - particularly if it goes above Tg. Do you know the Tg of your material? In any case, you could try CryoMill. Solid way to keep your sample really cold.grinding of polymers,Plastic Grinding At Pro Polymers - Morgan UtahDec 19, 2010 .

Qualitative and Quantitative Analysis with Grinding Polymers - AZoM

Sep 29, 2016 . For this particular analysis, the method mentioned above was discovered to be the most effective grinding program for PP fleece materials. In this program, the material does not become warm enough to decompose or lose its brittleness during short grinding and it provides a yield of between 80 and 90%.
