Expanded Polystyrene (EPS), is a perfect termoplastic isolation material gained due to expanding gas and polymerization of styrene. In the numerous microscopic closed pores (in 1m² EPS-3-6 billion pores holds a plenty of stationary air. As is known that stationary air is one of the best heatinsulation materials, quality EPS is provided by this feature. In a kind of that the material consists 98% of air, it is easy and not deals additional weight to a building. Having given the necessary form it is possible to use both in heat insulation and in the packing industry.
