Trials to introduce permanent changes in polymers by means of Cryogenic Mechanical Milling (CMM) with the Freezer/Mill® were started with two polymers; isotactic polypropylene (iPP) and syndiotactic polystyrol (sPS). After melting and re- crystallization, both cryogenically ground (i.e.at –
Unlike softer plastics, polycarbonate retains its rigidity and strength during bead beating. Extremely durable, polycarbonate vials can be submersed in liquid nitrogen and immediately used for cryogenic grinding. Solvent-resistant polyethylene-lined polypropylene caps are recommended when wet grinding with solvents or buffers.
Cryogenic Grinding - Grinding tough, thermoplastic materials at cryogenic temperatures means that plastics are brittle enough to be ground to very fine particles sizes. Temperature Control - Cryo-Grind systems inject controlled amounts of liquid nitrogen to regulate the heat of the grinding mill and allow higher material throughputs at any time ...
