Polystyrene - Wikipedia
Polystyrene (PS) / ˌpɒliˈstaɪriːn / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] . Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. [6] .
