Description
Product: T-GPPS 1160
Description: GPPS 1160 is a high heat resistance and molecular weight crystal polystyrene for extrusion and biaxially oriented polystyrene (OPS) industry. It is particularly useful in thick sheet production through direct inject gassing, resulting in expanded sheets with high mechanical properties. It can also be diluted with HIPS 7240 for sheet extrusion suitable for thermoforming.
Applications: Shower cabinets, lighting thin films, insulation boards, foam sheets for fruit trays, meat trays, and egg boxes.
