Material Notes:

LACQRENE® 2551 is a high heat resistance, medium impact polystyrene for injection molding. The very high Vicat Softening Point of this grade gives moldings of high rigidity and a good dimensional stability at high operating temperatures. The fast set-up of this grade allows for the production of thick molding with reduced sink marks.ApplicationCD boxes, Disposable razors, Audio cassettes, Cosmetics packaging, Disposable cutleryInformation provided provided by Total Petrochemicals.Total Petrochemicals includes former Fina and Atofina plastics product lines.
