Product name: Sodium metaantimonate
Molecular formula: NaSb03
Molecular weight: 192.73
Physical and chemical properties: white powder with granular crystals and equiaxial
crystals.High temperature resistance, does not decompose at 1000℃ .Soluble in
tartaric acid, sodium sulfide solution, concentrated sulfuric acid, slightly soluble in
alcohol, ammonium salt, insoluble in acetic acid, dilute alkali and dilute inorganic
acid.Insoluble in cold water, hydrolysis occurs in hot water to form colloids.
Product category: Inorganic saltUsage: Sodium metantimonate (Nasb203) is the best flame retardant, used in the manufacture of plastics and
rubber parts in the manufacture of automobiles, high-speed rail, aircraft and home appliances.Improve high
temperature resistance, flame retardant and aging resistance of components.Especially in the new energy
vehicles, ABS, PST, PET, PE, PS, PP and other components manufacturing, its role is irreplaceable.Under high
temperature combustion, the material remains insoluble and non-burning, effectively curbing the fire and
ensuring the safety of the vehicle.It is also widely used in paint and textile manufacturing to increase the flame
retardancy and fire resistance of the coating.It can effectively increase the signal transmission speed in the
production of optical fiber materials and electronic components.
