Styrofoam – The original Extruded Polystyrene (XPS) product
STYROFOAM™ was manufactured by Dow from the 1940s to 2018. In 2018 Dow Chemical sold the rights to the EU XPS business to leading plastics specialist Ravago.
The process of extruding foamed polystyrene results in a material with uniformly small, closed cells, a smooth 'skin' and an unrivalled set of properties which make it the choice of specifiers in a wide range of demanding insulation applications.
Dow Chemical (Ravago), the leading XPS manufacturer has developed new technology to significantly improve the thermal resistance of Styrofoam. This has resulted in a new product type called XENERGY™ Styrofoam.

Available in a range of sheet sizes and thicknesses from 6-165mm, Ravatherm XPS H LB (previously Styrofoam LBHX) boards have a calibrated dust free surface that provides an excellent key for lamination. Ideal for production of composite panels due to Ravatherm’s unique high strength in compression, tension, bending and shear. The high strength to weight ratio is particularly important in applications such as commercial vehicles. Due to its homogenous cell structure and uniform density Ravatherm can be cut very accurately and to very close tolerances. The closed cell structure ensures that Ravatherm retains its performance even when in permanent contact with moisture. Ravatherm material is resistant to most acids and salts, it does not rot and its thermal and mechanical properties have been proven long-term. Ravatherm XPS H LB provides reliable and durable thermal insulation performance.
