This invention relates to the field of processing foaming polystyrene compositions. The invention permits a threefold increase in toughness, while simultaneously reducing the material density by 15% due to the foaming of a precompressed concentrate containing polystyrene, azodicarbonamide, zinc stearate, zinc oxide, stearic acid, dioctyl phthalate, to a density of 0, 98-1.08 g / cm, then mixing it with polystyrene and pouring under pressure. 2 hp f-ly. 3 tab. i (L |
