Zusammenfassung:Particle-shaped expandable styrol polymers that can be processed to hard foamed material having a low density and a fine cellular structure and containing a foaming agent and aluminium in the form of particles, which are reflecting infrared rays and this styrol polymer particles are homogeneously distributed in particle of styrol polymer. Method for the production styrol polymers by polymerization styrol and foaming agent in reactor, where during this polymerisation process,the aluminium articles are added in the polystyrol carrier to the limit 6 % weight, in which general participation has a laminar shape in the form of the concentrate. Časticové expandovateľné styrénové polyméry spracovateľné na tvrdé peny s nízkou hustotou a s jemnou bunkovou štruktúrou obsahujú nadúvadlo a hliník vo forme častíc, ktoré odrážajú infračervené lúče,pričom tieto častice hliníka sú homogénne distribuované v granulách styrénového polyméru. Spôsob prípravy styrénových polymérov polymerizáciou styrénu s nadúvadlom v reaktore, pričom v priebehu polymerizácie sa pridajú hliníkové častice v polystyrénovom nosiči v množstve max. 6 % hmotn., ktorých hlavný podiel má tvar platničiek, vo forme koncentrátu.
