  • Size Reduction – General Polymer Services

    The cryogenic size reduction process, also known as "cryomilling", involves exposing the resin pellets to temperatures of -100° Centigrade or lower. These temperatures lead to finer grains, as they make even the most elastic polymers more brittle. This environment also suppresses recovery and recrystallization. Some materials suitable for cryomilling include:
