FIELD: chemistry.

SUBSTANCE: invention relates to a polymer material, particularly a thermoplastic elastomer, which contains a halogen-free fire-retardant which is included in a polymer matrix. The fire-retardant contains (A) coated ammonium polyphosphate(s) in a crystalline modification II and/or derivatives thereof and (B) an oligomer or polymer derivative of 1,3,5-triazine or mixtures of several such derivatives. The fire-retardant also contains at least one compound selected from (C) phosphates, pyrophosphates, polyphosphates, organic and inorganic phosphonates and phosphinates, stannates, molybdates or borates of elements of main subgroups II, III, IV or elements selected from Fe, Zn, Ti, Mn, Zr, Mo and (D) pre-condensed malamine derivatives, melamine salts and adducts thereof, ethylenediamine phosphate, piperazine phosphate, piperazine polyphosphate, 1,3,5-trihydroxyethylisocyanurate, 1,3,5-triglycidylisocyanurate and triallylisocyanurate. The weight ratio of component A to component B ranges from 10:1 to 1:1 and content of components A and B together ranges from 60 to 99 wt %, and content of components C and D together ranges from 1 to 40 wt % of the total weight of components A, B, C and D. Content of chlorine in component B is less than 1 wt % and/or content of chlorine in the entire polymer material is less than 1500 ppmw.

EFFECT: fire-retardant can be used in lower concentrations with high fire-retardant action, has low water-solubility and decomposes at higher temperatures compared with existing fire-retardants.
