Toll Grinding - Abifor

Toll Grinding: The manufacture of thermoplastic powders with the addition of liquid nitrogen (N2), also called cryogenic grinding, requires not only significant know-how but also state-of-the-art equipment. During the past 2 years, Abifor has invested significantly

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.
