HIPS – high-impact polystyreneHIPS (high-impact polystyrene) is a block-copolymer of styrene with rubber. When not modified PS is a fragile material and its specific impact viscosity does not suit many applications. High-impact PS is more flexible, and it has higher impact-resistance but lower tensile strength and thermal stability, compared to unmodified PS. For in-depth analysis we seldom refer only to the Foreign Trade Code (Group 3903), but we make our own more precise correlation of HIPS types by each grade of each producer. Regular analytics on the HIPS market is available in the following Reports:
