Benefits of Expanded Polystyrene


Styrofoam is usually confused with disposable cups and food containers. Styrofoam (XPS or Extruded Polystyrene) is a trademarked, closed-cell type of extruded polystyrene foam. This is majorly used for thermal insulation and craft purposes. Extruded polystyrene, also known as styrofoam, is recommended for use under concrete slabs, edge beams, green roofs, cavity walls, external walls and even cool rooms. It is lightweight and also water-resistant.

Expanded Polystyrene

One of the most widely used plastics, Expanded Polystyrene (EPS), has been a material of choice that is used for over half a century due to its technical versatility and durability. It is widely used in an array of daily applications. Polystyrene is environmentally friendly and recyclable and can be shaped into literally anything that is needed. EPS is also an excellent choice for insulation and packaging supplies.


Styrene Monomer is a colourless, oily liquid substance with a sweet smell. This kind of plastic is used in the production of polystyrene plastics and resins. Styrene products can be used to make a wide variety of products like pipes, car parts, food containers, carpet backing and more. It is also used mainly by plastics manufacturers, paints, sealers and more.

Polyurethane (PU)

Polyurethane (PU) is one of the most popular choices of material when it comes to surfboard crafting. It is a denser product and simpler to shape than polystyrene. However, this material can be dangerous. If correct precautions are not taken, it can be highly toxic to work with. This kind of plastic is more dangerous to the environment and cannot be recycled. Therefore, the best-recommended plastic is polystyrene.
