EPS beads have a very low density, with some sources indicating a density of less than 33 kg/m3. This makes them lightweight and easy to handle, especially when used as an aggregate or in construction applications.
The low density and closed-cell structure contribute to excellent thermal insulation properties, making them effective in reducing heat transfer and improving energy efficiency in buildings.
The structure of EPS beads provides excellent shock absorption,used as lightweight, cushioning packaging material to protect fragile items like electronics and appliances during transport and storage.
