GPPS1160 is a high heat resistance, high molecular weight crystalline polystyrene used in the extrusion industry. It is most suitable for production of Oriented Polystyrene (OPS). It is particularly useful for production of thick sheet by direct gassing, where it gives expanded sheets with high mechanical properties.
Extrusion Applications:
Shower cabinets; Lighting thin films; Diluted with high impact polystyrene for thermoforming, it shows resistance against high temperatures. In line extrusion/thermoforming of transparent cups.
Direct gassing Applications:
Insulation board; Foamed sheet for thermoforming of fruit trays, meat trays, egg boxes.
Characteristics: High heat resistance, high mechanical properties
