What is EPS(Expandable Polystrene)?

EPS is a typically thermoplastic, foamy, closed porous, white colored thermal insulation material that is obtained from petroleum.
In EPC (Expanded Polystyrene Rigid Foam) products that are obtained by expanding the polystyrene particles and fusing to each other, expanding gas used for expanding the particles and obtaining the foam is “Pentane”. Pentane, after providing the formation of numerous small pores inside the particles, displaces with the air in a very short period of time during and after production.

Thus still air is confined in numerous (3-6 billion in 1 m3 EPS) closed porous cells in EPS plates. 98% of the material is still and dry air. Still and dry air is the best known economic, environmentally frendly and a perfect thermal insulation material. Economic and superior thermal insulation properties of EPS thermal insulation plates are provided in this way. 

EPS, one of the various materials providing the existing best thermal insulation, is the only material that provides the same performance more economically than the other thermal insulation materials used in our country.

Production not being energy-dense is another important reason why it is affordable despite its superior technical properties. Besides its efficient mechanical resistance; the replacement of the expandable gas with the air in a very short period of time, provides the product performance to be constant during its lifetime.

Its thickness does not become thin, its thermal conductivity does not increase and no degradation occurs in its properties. In the molding stage of EPS production which is the final stage; it is provided to have the particles fused together tightly. The success of this application is understood from the honey comb appearance of the particles on the surface of the product. EPS is produced with requested densities. Because its properties can be changed with its density as requested, it does not cause any material loss and unnecessary cost increases. 

EPS plates that are generally used for insulation purposes at 15-30 kg/m3 densities, are very light and they can also be produced as composite elements by coating with other materials. EPS is an eco-friendly product in every phase; it does not damage the ozone layer, does not cause climate changes, the energy does not need dense production and it is substantially a recycable product. EPS products are used widely in thermal and sound insulation of the structures and in packaging industry as plates, pipes or pre-molded elements.

Also EPS products have unlimited usage areas that cannot be counted in all the applications with the importance of easy molding, easy application and low thermal insulation as from using as a wall material in the buildings to the insulation of cold room storages, highway construction in cold zones, reinforcement of the surfaces, production of life buoys and life jackets for the ships.
