Polystyrene (PS)

Polystyrene (PS) is a crystal clear amorphous commodity. The polymerization of styrene results in a transparent, rigid and hard plastic with a high gloss finish. Unfortunately, it is very brittle. Sacrificing the transparency and stiffness it can be mixed with 5 – 10% butadiene rubber (BR) to get what is called high impact polysyrene (HIPS), with an impact strength of up to 5 times higher than standard polystyrene.

PS Properties

  • Low material cost
  • High transparency (88%)
  • Negligible moisture absorption
  • Food approved grades are available
  • High hardness and surface gloss
  • Brittle
  • Poor chemical resistance
  • Low softening temperature
  • Turns yellow if left outdoors
