Material Notes:
4440 is a high impact polystyrene for the injection molding of parts demanding good dimensional stability at high temperatures, particularly front and back covers for television sets. In addition, the flow properties of this grade make it particularly suitable for the molding of large parts and for use with new techniques such as gas injection.Applications: Television front and back covers, Office equipmentInformation provided provided by Total Petrochemicals.Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
