EPS raw material is expanded polystyrene, which is the raw material of foam. Granulated, foam material is formed after foaming, and now we see foam for electrical packaging and bowls for fast food soup.

Expanded polystyrene, also known as expandable polystyrene

Polystyrene (EPS) has the advantages of low relative density (1.05 g/cm), low thermal conductivity, low water absorption, impact and vibration resistance, heat insulation, sound insulation, moisture resistance, vibration reduction, and excellent dielectric properties. It is widely used as a shockproof packaging material for mechanical equipment, instruments, household appliances, handicrafts, and other fragile and valuable products, as well as for the packaging of fast food.
