Composition of flame retardant and smoke suppressant

White or pale yellow, transparent orthorhombic crystals. Density 4.692g/cm3. Melting point 795 ℃. Boiling point 1155 ° C (sublimation). It turns yellow when heated and recovers when cooled. Even below the melting point, there is significant sublimation. Insoluble in water, soluble in ammonia and strong alkali. Jiangsu Sodium Molybdate manufacturers react with alkaline solutions and many metal oxides to form molybdates and polymolybdates.

Jiangsu sodium molybdate is used as a high-efficiency flame retardant and smoke suppressant, which is more effective for chlorine-containing adhesives. The reference dosage of 0.5 to 5.0 parts can reduce the amount of cigarette smoke by 30% to 80% and increase the oxygen index by 10% to 20%. Molybdenum compound, copper oxide, iron oxide, cadmium oxide, zinc oxide, etc. are used in combination with synergistic effect, and its smoke suppression effect is better than that of single MoO3. The flame retardant and smoke suppressant of Jiangsu sodium molybdate manufacturers is mostly a mixture of molybdenum oxide and Ammonium Molybdate.
