Answer:

The raw material of the Polystyrene has a density of around 1.05 g/l, or kg/m3 . which is a little bit more than water's

Regarding the processed material there are two main types of polystyrene density-wise;

EPS = Expanded PolyStyrene:

most used in the range of: 10 - 50 g/l

EXPS or XPS = EXtruded PolyStyrene:

most used in the range of: 25 - 45 g/l
