Total PSC 1810/1811 Polystyrene
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Molded, Unreinforced
Material Notes:	1811 is a very easy flowing crystal polystyrene designed, principally, for the injection molding industry. The excellent processing characteristics of this grade allows for the production of articles which are very thin and/or have complex flow patterns. In extrusion, 1810 is used as a high capping layer in co-extrusion. 1810 is not externally lubricated. Application Information provided provided by Total Petrochemicals. Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
