Rigid/Solid Polystyrene Production Process


Polystyrene (PS) is a valued plastic used in many everyday items. The resin identification code for this plastic is "6." PS (solid or foamed) starts as a liquid monomer and is transformed into a stable, solid polymer. It’s then used to produce cups, containers, and cutlery through thermoforming or injection molding.
