Expandable Polystyrene (EPS) beads are a key raw material for producing lightweight foam products in the packaging, construction, and insulation industries. The global EPS market has steadily expanded over the past decade, with production increasing especially in Asia-Pacific, where rising urbanization and infrastructure investments are driving demand for insulation boards and protective packaging. China, South Korea, and Taiwan are dominant players in EPS bead manufacturing, supported by mature petrochemical supply chains. Production volumes are projected to grow around 4% per annum through 2025, especially in emerging economies where building insulation is becoming mandatory due to energy efficiency codes. The packaging industry’s demand for lightweight protective foams is another significant driver. Technological upgrades and capacity expansions in the Middle East and Southeast Asia will further support global production and help stabilize supply.
