Yes you can convert polymer pellets into powder form using cryogenic grinding apparatus where the pellets are kept at 196 degrees centigrade in l 183 5The 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 grindin1Dear allI dont understand if grinding itself is the subject or to get a powder4121
True cryogenic grinding is a different process designed to exploit the tendency of many materials to become brittle at low temperatures In grinding plastics and rubbers for example the polymers to relax The effect is pronounced for some grades of polypropylene cooling from 20176C to4555
In addition cryogenic grinding enables size reduction of the pellets without adding any additional heat history above ambient temperatures to the polymer This is beneficial for some polymers and also can enhance the color of the final product4459
