Polypropylene foam

 Very similar in appearance to expanded polystyrene

Identifiable differences are

  • Expanded polystyrene’s beads will easily separate when rubbed.
  • Expanded polystyrene has a dry feel when touched.
  • Expanded polyethylene’s is waxy to the touch.
  • Expanded polyethylene’s beads will not separate easily.
