### Overview of Expanded Polystyrene: Composition and Properties
Expanded Polystyrene (EPS) is a lightweight, rigid, and foam-like material that has gained significant traction in various industries due to its versatility and excellent insulation properties. EPS is primarily composed of polystyrene, a synthetic aromatic hydrocarbon polymer made from the monomer styrene. The transformation of raw polystyrene into EPS involves a unique process of expansion and molding, which contributes to its distinctive structure and myriad applications.
**Composition of Expanded Polystyrene**
EPS is manufactured by the polymerization of styrene monomers with the inclusion of pentane, which serves as the blowing agent. During production, small beads of polystyrene are pre-foamed using heat. The foaming process leads to the expansion of the beads to about 20 times their original volume. Following this, the expanded beads are fused together in a mold, where they expand further and assume the shape of the mold to create solid blocks or shapes of EPS.
The resulting material is characterized by a closed-cell structure consisting of up to 95% air. This significant air content is what makes EPS both lightweight and an effective insulator, offering a thermal resistance (R-value) that is superior to many other materials. The density of EPS is generally low, varying between 10 to 40 kg/m³, depending on the intended application and manufacturing process.
**Properties of Expanded Polystyrene**
