FIELD: chemistry.
SUBSTANCE: invention relates to foamed polyurethane obtained by cross-linking: (a) polyisocyanates, (b) high-molecular weight compounds with groups that are reactive with respect to isocyanate groups, having average functionality of less than 2.5, (c) particles of a solid substance from radically polymerised polymers, dispersed in one of the high-molecular weight compounds with groups that are reactive with respect to isocyanate groups (b), (d) a blowing agent, (e) a chain-elongating agent, optionally a cross-linking agent or mixture thereof, (f) a catalyst and (g) optionally other additives, to form a reaction mixture and carrying out the reaction, wherein content of the chain-elongating agent is less than 6 wt % per total weight of components a) to f), and content of particles of the solid substance is higher than 15 wt % per total weight of components a) to f). The present invention also relates to a method of producing said foamed polyurethane, integrated foam plastic containing said foamed polyurethane, and use of such integrated foam plastic as a shoe sole.
EFFECT: obtaining foamed polyurethanes, having better sliding resistance, higher fatigue strength during repeated bending even at low temperature and tactility similar to that of rubber.
