Total PSC 1160/1160N Crystal Polystyrene
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Transparent Grade
Material Notes:	1160 is a high resistance, high molecular weight crystal polystyrene mainly for the extrusion industry. Most notable for the production of bi-oriented polystyrene (BOPS). It is particularly useful in the production of thick sheet by direct gassing, where it gives expanded sheets with high mechanical properties. LACQRENE® 1160 can be used in dilution with LACQRENE® for the extrusion of sheet for hot-fill thermoforming applications. Applications: Formed trays, Shower screens, High heat resistant thermoformed products, Transparent cups Information provided provided by Total Petrochemicals. Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
