PS (Polystyrene)

PS (Polystyrene)

PS is a general-purpose thermoplastic polymerized from styrene monomer, a long-established transparent plastic with extremely broad applications.

Product Portfolio

• GPPS (General-Purpose Polystyrene): injection and extrusion grades — transparent and rigid for food containers and stationery.
• HIPS (High-Impact Polystyrene): injection and extrusion grades — impact-resistant for appliance housings and toys.

PS is colorless and transparent, with a density of 1.05 g/cm³, a melting point of 212℃ and a glass transition temperature of 80-100℃. The family includes General-Purpose Polystyrene (GPPS) and High-Impact Polystyrene (HIPS), widely used for disposable containers and foam food boxes thanks to its water resistance and chemical resistance. PS is a common plastic material prized for its transparency and processability.
