Beschreibung
Zusammenfassung:	FIELD: fire extinguishing. SUBSTANCE: invention relates to aerosol involving fire-extinguishing technique. Composition includes 10-19 wt % of epoxide resins and/or thermoplastic polymers û vinyl alcohol derivatives with vitrification temperature above 25 C, 70-84 wt % of potassium nitrite/potassium perchlorate mixture at ratio 1:0.9-1.2), and special additives: plasticizer, burning modifier, and process additives. Plasticizer can be dibutyl phthalate, dibutyl sebacate, glycerol triacetate, or their mixture. As burning modifier, manganese dioxide, nickel oxide, ferric oxide, cupric oxide, carbon or their mixture are used. EFFECT: improved working characteristics of composition at reduced specific uptake thereof due to increased completeness of the combustion. 3 cl, 1 tbl
