   CD case made from general purpose polystyrene (GPPS) and high impact polystyrene (HIPS) Disposable polystyrene razor Polystyrene (PS) is used for producing disposable plastic cutlery and dinnerware , CD "jewel" cases , smoke detector housings, license plate frames, plastic model assembly kits, and many other objects where a rigid, economical ...

4. Rubber toughening - Wikipedia

   en.wikipedia.org/wiki/Rubber_toughening

   The most widely used version of toughened polystyrene is called high impact polystyrene or HIPS. Being cheap and easy to thermoform (see thermoforming), it is utilized for many everyday uses. HIPS is made by polymerizing styrene in a polybutadiene rubber solution. After the polymerization reaction begins, the polystyrene and rubber phases separate.

8. Toughening - Wikipedia

   en.wikipedia.org/wiki/Toughening

   In high-impact polystyrene (HIPS), the elastomeric dispersion is used to improve crack propagation resistance. When main crack propagates, microcracks form around elastomeric dispersion above or below the fracture plane. The HIPS is toughened by additional work associated with formation of microcracks.
