Polystyrene (PS)

Polystyrene (PS) Materials

Polystyrene, or PS is a commodity resin mainly used in the form of lightweight, rigid foams and films, but also available in regular polystyrene plastic. It is versatile, easy-to-process and an economical polymer that offers a lightweight but durable material with strong insulation properties. Known for its hardness and thermal stability, it is nonhygroscopic, naturally transparent, amorphous and can be used in injection molding, blow molding and extrusion. Polystyrene foam materials contain two types known as expanded polystyrene and extruded polystyrene. Polystyrene’s strong chemical resistance and mechanical properties make it ideal across many industries and applications.
