What are the differences between expanded polystyrene and polystyrene, and how do these differences impact their respective uses and applications?

Answer 1

Expanded polystyrene (EPS) is a lightweight, rigid foam material made by expanding polystyrene beads. It is commonly used for insulation, packaging, and construction due to its excellent thermal insulation properties and shock-absorbing capabilities. Polystyrene, on the other hand, is a solid plastic material that is more rigid and dense than EPS. It is often used in food packaging, disposable cups, and other products requiring a solid plastic material. The differences in density and structure between EPS and polystyrene impact their uses and applications. EPS is preferred for applications requiring lightweight insulation and cushioning, while polystyrene is better suited for products that need a more solid and rigid material.
