Product type
Expanded Polystyrene (EPS) is a lightweight, rigid plastic foam material produced from solid beads of polystyrene. It is created through a process of expansion and molding, resulting in a closed-cell structure that provides excellent insulation properties. EPS is commonly used in packaging, construction, and various industrial applications due to its durability and thermal resistance.
| Density | 8 to 30 kg/m³ |
| Thermal conductivity | 0.030 to 0.040 W/m·K |
| Compressive strength | 50 to 300 kPa |
| Water absorption | Less than 0.5% by volume |
| Flammability rating | Class E (EN 13501-1) |
When selecting Expanded Polystyrene, consider the density and thermal conductivity that best meet your application requirements. Specify the desired compressive strength and any necessary flammability ratings based on industry standards. Additionally, provide information on the quantity needed and any specific certifications or grades required for your project to ensure compliance with regulations.

EPS is made from expanded beads and has a lower density, while XPS is extruded and has a higher density and moisture resistance.
Yes, EPS can be recycled, but availability of recycling facilities may vary by location.
EPS typically performs well in temperatures ranging from -40°C to +70°C.
Yes, but it should be protected from UV exposure to prevent degradation.
EPS is manufactured by expanding polystyrene beads using steam, which are then molded into desired shapes.
EPS is often used for insulation in walls, roofs, and foundations, as well as for lightweight fill material.
