High Impact Polystyrene (HIPS), commonly known as "antishock" in the market, is a high-impact resistant polystyrene. It is the most versatile plastic sheet available that can be processed smoothly, offers freedom in molding, provides increased impact resistance, and significant cost advantages. It is the material of choice for vacuum formers and screen printers who want to produce quality work on limited budgets.

High Impact Polystyrene (HIPS) sheets find a wide range of applications from covering bathroom cabinet doors to bathtub front panels, from sales stands to car roof racks, and furniture parts. The absence of crystallization energy allows for rapid heating and cooling, thus providing the advantage of quick molding. It can be easily molded without degradation using low energy through extrusion and injection molding methods.
