Expanded Polystyrene (EPS) blocks are lightweight, rigid plastic foam materials made from expanded polystyrene beads, commonly used for high-performance thermal insulation, protective packaging, and structural geotechnical fill. They are valued for being cost-effective, durable, moisture-resistant, and easy to cut or shape.
Key Features and Benefits
Insulation: Exceptional thermal resistance (R-value) for energy-efficient construction.
Lightweight: Easy to handle, transport, and install, often weighing only 1% of traditional materials like soil or concrete.
Durability: High compressive strength, particularly in higher densities (20–30+ kg/m³), suitable for load-bearing applications.
Versatility: Available in various sizes and densities, and can be customized with additives for fire resistance.
Main Applications
Construction: Used as insulation panels, roofing, wall insulation, and lightweight void fillers in buildings.
Geofoam: Used in civil engineering for road construction, bridge abutments, and slope stabilization.
Packaging: Provides excellent shock absorption for protecting fragile items.
