Material Notes:

LACQRENE® 4240 is a high heat resistance, high impact polystyrene for the extrusion industry. Good mechanical and thermal properties leads to the production of thermoformed articles of good rigidity and toughness with improved temperature performance. LACQRENE® 4240 finds applications in injection blow molding. LACQRENE® 4241 is a high impact polystyrene for the injection of articles of good dimensional stability at elevated temperatures, e.g. TV. molding.ApplicationSheet for thermoforming, Industrial sheet, Sanitary ware, Profiles, TV molding, Shoe heels, Reels and spools, Flower potsInformation provided provided by Total Petrochemicals.Total Petrochemicals includes former Fina and Atofina plastics product lines.
