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.
