G 3160 is a high molecular weight general-purpose polystyrene (GPPS) engineered to deliver superior heat resistance and robust mechanical performance. Its balanced properties make it highly adaptable for various manufacturing techniques, including direct gassing extrusion, biaxially oriented film and sheet, and glass-clear panels.

This grade is also well-suited for injection molding, particularly for medium wall-thickness transparent components. The result is consistently bright, neutral-colored parts that meet the aesthetic and structural expectations of sophisticated markets.

GPPS 3160 excels across multiple sectors due to its clarity, dimensional stability, and ease of processing. It is a trusted choice for manufacturers producing foamed packaging trays, clear panels for shower cubicles, insulation boards (XPS), transparent refrigerator components, and medical-grade items.
