Tribasic Lead Sulfate(TBLS)

Descriptions of the tribasic lead sulfateMolecular formula: 3PbO·PbSO4·H2O Properties:Tribasic Lead Sulfate is white or light yellow powder. It has slight sweetness while it is toxic. The density is 7.1 and the melting point is 820 . When the temperature goes up to 200, tribasic lead sulfate will begin to lose crystal water. Its refractive index is 2.1.

Tribasic lead sulfate can not dissolve in water and organic solvents but it can dissolve in hot acetic acid, ammonium bases, as well as nitric acid and hot concentrated hydrochloric acid.Without flammability and corrosion, tribasic lead sulfate is easy to moisture. Under the damp state, the product can change color and decomposite when melt with sunshine.

It has a stabilizing effect on PVC and has excellent heat resistance and electrical insulation as well as the lightfastness. Tribasic lead sulfate is especially suitable for high-temperature processing.Quality Indicators:(in line with the HG2340-92)Item Best quality First quality Qualified Product

Applications of the tribasic lead sulfate:The tribasic lead sulfate can be used as the thermal stabilizer of PVC. It can used in the rigid PVC pipes, plates and injection molding products as well as soft artificial leather products.

Due to its excellent performance, it is widely used in PVC electrical insulation materials, especially in the production of wires, cables and so on. This product can also be used in the pigment of paint. It has advantages of light stability and fixed color
