Expanded Polystyrene (EPS) is a lightweight, rigid, and closed-cell foam plastic material composed of 98% air and 2% petroleum-derived raw material. It is manufactured by expanding solid polystyrene beads using a blowing agent like pentane under steam pressure, causing them to swell up to 50 times their original size before being molded into blocks or custom shapes. Due to its high performance and cost-effectiveness, it serves as a staple material in global packaging, construction, and insulation industries. Core Physical and Mechanical Properties
