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. GPPS1160 can be used in combination with HIPS7240 for the extrusion of sheet for hot-fill thermoforming application.
Applications:
GPPS-1160 extrusion: 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: Insulation board; Foamed sheet for thermoforming of fruit trays, meat trays, egg boxes.

Storage: GPPS1160 should be stored in dry and dust free environment at temperature below 50°C.Exposure to direct sunlight should be avoided as this may lead to product deterioration.
GPPS-1460
GPPS1460 is a high heat resistance and molecular weight crystal polystyrene for extrusion and thick walled injection molding application. It is particularly useful in the production of thick sheet by direct inject gassing, where it gives expanded heets with high mechanical properties.
Product Description: GPPS-1540 is an easy flowing crystal polystyrene designed for extrusion or injection applications. In extrusion, it improves extruder output and thermoforming cycle times when mixed with a super high impact polystyrene such as HIPS7240. It is particularly suitable for glossy-layer co-extrusion.
Applications: Extrusion: Impact dilution; Gloss layer in co-extrusion; Anionic styrene butadiene copolymer dilution. Injection: Packaging articles; Medical applications, e.g., Petri dishes; Office equipment; Pen barrels; Crisper boxes for refrigerators; Cups.
