Impact Polystyrene

High impact polystyrene, hard, rigid, with an impact strength more than five times that of GPPS,  works well in a wide array of applications, including:

  • Refrigerator linings
  • Bathroom cabinets
  • Instrument control knobs
  • Closures
  • Toilet seats and tanks

The mechanical properties of high impact polystyrene vary greatly, depending on the type and percentage of rubber used to modify the original PS.
