Application

1. Its primary use is as a monomer for synthetic rubber and plastics, used to produce styrene-butadiene rubber, polystyrene, and expanded polystyrene.

2. It is copolymerized with other monomers to manufacture various engineering plastics for different applications.

3. Styrene-butadiene copolymer (SBS) produced through copolymerization with butadiene is a thermoplastic rubber widely used as a modifier for polyvinyl chloride and polypropylene.

4. It is used in the production of styrene-based resins and styrene-butadiene rubber.

5. It serves as a raw material for manufacturing ion exchange resins and pharmaceuticals.

6. It finds applications in the pharmaceutical, dye, pesticide, and mineral processing industries.
