Expandable polystyrene (PS-V), in English Expandable Polystyrene (EPS) is a traditional polystyrene with the addition of a foaming agent inside the granules - pentane gas. Each granule consists of evenly distributed microscopic dense cells filled with air. The result is a uniformly foamed mass with a very fine closed-cellular structure. 1 m3 of such material is 98% filled with air, enclosed in 3-6 billion closed cells.
Due to its internal structure, it has a very low thermal conductivity, close to that of stationary air (coefficient of thermal conductivity of air about 0.00006 cal / cm .sec. degrees, i.e. through each square centimeter at a temperature difference of 1 ° C and at a thickness of 1 cm. 0 is transmitted,
