Expandable Polystyrene (EPS) Resin
Premium-quality EPS beads for packaging, insulation, and industrial foam applications — trusted by manufacturers across India and 40+ countries.
What Is Expandable Polystyrene (EPS) Resin?
Expandable Polystyrene (EPS) resin is a versatile, lightweight thermoplastic material widely employed in packaging, thermal insulation, and industrial applications. Manufactured from polystyrene beads containing a blowing agent — typically pentane — these beads expand substantially when exposed to heat or steam, forming lightweight closed-cell foam structures.
At MarkoBenz, we produce high-quality EPS resin engineered to satisfy the demands of modern industries requiring durability, thermal efficiency, and dependable protective packaging solutions. Our beads deliver consistent expansion and reliable performance during the moulding process, serving manufacturers across packaging, construction, electronics, and cold-chain sectors.
