n (freeze grinding) Thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, cohere in lumpy masses, and clog screens. When chilled by dry ice, liquid carbon dioxide, or liquid nitrogen, thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes.
