More About Polystyrene Densities

We manufacture polystyrene in low, medium, high, and extra-high densities in South Africa. The density of the polystyrene affects how soft or hard the polystyrene is.

  • Low density polystyrene is very soft. (12 kg/m3) - Good for general use & packaging
  • Medium density polystyrene is harder (15 kg/m3) - Perfect for cavity wall insulation
  • High density polystyrene is even harder (20 kg/m3) - Perfect for below concrete floor insulation
  • Extra-High density polystyrene (highest density) is extremely hard (24 kg/m3 to 30kg/m3) - Good for hydroponics and concrete roof insulation
