GPPS/HIPS is mainly used in the fields of electronic appliances, daily necessities and office supplies.

General-purpose Polystyrene GPPS:
Polystyrene GPPS can be used in daily necessities, electrical appliances, instrument housings, toys, lamps, household appliances, stationery, cosmetic containers, indoor and outdoor decorations, fruit trays, optical parts (such as prisms, lenses), lens windows and moldings, car lights, telecommunications accessories, electric High-frequency capacitor films, high-frequency insulating materials, containers such as televisions, waveguides, chemical containers, etc.

Suspended polymeric resins can be made into foamed plastics of different densities, used as thermal insulation, sound insulation, shockproof, floating, packaging materials, cork substitutes, pre-foamed bodies can be used as water filter media and lightweight concrete, and low-foaming plastics can be made Synthetic wood for furniture etc.

High Impact Polystyrene (HIPS):
Polystyrene (HIPS) can be injection molded or extruded into various products, suitable for home appliance shells, electrical appliances, instrumentation accessories, refrigerator linings, panels, TV sets, radio cassette players, telephone casings, stationery, toys, packaging containers, daily necessities, furniture, Tableware, trays, cutlery, structural foam products, etc.
