Material Notes:

LACQRENE® 1250 is a very high molecular weight crystal polystyrene mainly for the injection molding industry. It is characterized by a very good compromise between molecular weight, heat resistance and fluidity. This results in excellent processing combined with good demolding properties and high mechanical properties. This allows reduced thickness and high processing speed.ApplicationCD boxes, Medical and laboratory items (Petri dishes, test tubes), Cosmetics packaging, LACQRENE® 1250 can also be used in extrusion for various applications.Information provided provided by Total Petrochemicals.Total Petrochemicals includes former Fina and Atofina plastics product lines.
