Total PSC 1960N Crystal Polystyrene
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Transparent Grade
Material Notes:	1960N is a high resistance crystal polystyrene with very high flow for the production of thick insulation board. The very low viscosity of this grade makes it particularly suitable for the production of insulation board with gases with zero ODP effect such as CO2 and HFC. The utilization of this grade pure, or mixed with other high heat resistance LACQRENE grades, allows the production of very thick insulation board (>10cm). This grade is not lubricated. Application Insulation board (5mm to 200 mm) Information provided provided by Total Petrochemicals. Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
