The Science Behind PS Polymers and Their Role in the Plastics Industry <br>Polystyrene is produced through a process called polymerization, where styrene monomers are linked together to form long chains of polymers. The resulting polymer chains have different molecular weights and structures, depending on the reaction conditions. PS polymers are widely used in the plastics industry due to their low cost, ease of processing, and versatility. They can be processed using various methods, including injection molding, extrusion, and thermoforming, to produce a wide range of products such as packaging materials, toys, and household appliances.
