FIELD: chemistry.
SUBSTANCE: claimed invention relates to product from extrusion foampolystyrene. Described is product from extrusion foampolystyrene, including polystyrene matrix, which determines cells; particles of halluazite clay, dispersed in polystyrene matrix in concentration higher than 0.1 wt.p. and 5 wt.p. or less counted per 100 part by the weight of entire polymer in polymer matrix; where particles of halluazite clay have size 1 micron or larger and 50 microns or smaller; and where fosmpolystyrene has monomodal distribution of cells by sizes and contains 50 wt.p. or less of all cations, different from barium cations, counted per one million of parts of the entire polymer in polystyrene matrix.
EFFECT: manufacturing product from extrusion foampolystyrene with improved quality of surface.
