Used primarily in the production of polystyrene, a versatile plastic found in packaging, disposable containers, and insulation materials. It is also a key component in the manufacture of synthetic rubber, such as styrene-butadiene rubber, widely used in tires and automotive parts. Additionally, it serves as a building block for copolymers like ABS (acrylonitrile butadiene styrene), which is utilized in electronics, automotive components, and household appliances. In construction, it is employed in the production of fiberglass composites and insulation products. Furthermore, it plays a role in the creation of resins and coatings for industrial and consumer applications.
