Expanded Polystyrene (EPS) foam is a type of plastic material that is made from expanded polystyrene beads. The beads are heated and fused together to create a lightweight, rigid foam with a closed-cell structure. EPS foam can be produced in different densities for various applications, ranging from 10kg/m3 to over 30kg/m3.

One of the key characteristics of EPS foam is its excellent insulation properties – making it an ideal choice for use in construction projects as well as packaging materials. Its low thermal conductivity helps to reduce heat transfer through walls and roofs, leading to energy savings and lower CO2 emissions.

Another benefit of EPS foam in Hawaii is its resistance to moisture, which means it can withstand exposure to damp conditions without losing its shape or structural integrity. This makes it perfect for use in areas where humidity levels are high, such as swimming pools or coastal locations.

EPS foam comes in various types, each uniquely created to cater to specific applications. The two main classifications of EPS foam are expanded polystyrene (EPS) and extruded polystyrene (XPS). While both have similar properties, they differ in terms of manufacturing processes.

Expanded Polystyrene (EPS) foam is made by expanding polystyrene beads using steam and then molding them into the desired shape. This type of EPS foam has a lower density than XPS and is ideal for insulation, packaging materials, and disposable food containers.

On the other hand, Extruded Polystyrene (XPS) foam is formed by melting plastic pellets under high pressure before being extruded through a die where it cools rapidly. Its closed-cell structure makes it denser and more rigid than EPS Foam making it suitable for use as an insulating material in construction projects such as roofs, walls, or flooring.
