Polystyrene

Polystyrene

Polystyrene (PS) is produced from styrene monomer, which in turn is produced from benzene and ethylene. Styrene is a liquid and is easily transported long distances, so PS plants do not have to be located near their main feedstock, styrene monomer. Many PS plants consist of multiple lines, with one line optimized for General-purpose polystyrene (GPPS) and the other line optimized for High-impact polystyrene (HIPS) production.
