FIELD: chemistry.
SUBSTANCE: invention refers to production of materials used for fire protection of facilities. Polymeric composition for fire-protective foaming material includes chlorine-containing polymer (chloroprene rubber, polyvinyl chloride, perchlorvinyl resin, chlorosulfonated and/or chlorinated polyolefin), plasticizer (chloroparaffin, trichloropropyl phosphate, tricresyl phosphate), intercalated graphite and ammonium salts as foaming fillers (ammonium chromate, ammonium carbonate, ammonium polyphosphate) and also mixture of melamine, paraform and oxalic acid taken is prescribed ratio.
EFFECT: invention provides a polymetic composition for production of fire-protective foaming coatings and separators with low initial foaming temperature (below 250°C).
