What is Styrofoam?

Styrofoam is an extruded polystyrene and is uniquely identified by its blue colour. It was first developed and produced in the 1940’s by Dow Chemical in the USA. The process of extruding polystyrene results in a material with uniformly small, closed cells and an unrivalled set of properties which make it ideal for insulation and also as a core in lightweight structural panels. Styrofoam combines low thermal conductivity and low water absorption to make it the choice of specifiers in a wide range of demanding insulation applications.

Styrofoam also has excellent mechanical properties including high strength in compression, tension, bending and shear  which are essential for a  core material in structural panels used in a range of markets including coldstores, touring caravans, truck panels, building and curtain-walling. The small uniform cell structure of Styrofoam is also ideally suited for use in markets such as hobby and craft where traditional modelling tools can create three-dimensional models.
