Description
Product: T-GPPS 1460
Description: GPPS 1460 is a high heat resistance and molecular weight crystal polystyrene designed for extrusion and thick-walled injection molding applications. It’s especially suitable for thick sheet production by direct inject gassing, providing expanded sheets with high mechanical properties.
Applications: Insulation board (XPS), foam sheets for food & fruit trays.
