By 2030, China is expected to become the only country responsible for all global growth in polystyrene production capacity. Between 2025 and 2030, China will add 1.21 million tons of new capacity every year through three planned projects and one additional announced development.
Polystyrene is a lightweight, cost-effective plastic known for its strong insulation properties and is widely used in packaging, building insulation, and foodservice products. According to GlobalData, demand in China — the world’s largest manufacturing economy — continues to rise, driven by the need for packaging materials for both domestic consumption and export markets.
