dioxobis(stearato)dilead - Reference Information
| chemical properties | white powder. Relative density 2.15, melting point> 280 ℃(280-300 ℃ decomposition), refractive index 1.60. Soluble in ether, insoluble in water. |
| use | this product is polyvinyl chloride stabilizer. Lead stabilizer is the earliest stabilizer used for polyvinyl chloride, and it is still used in large quantities. The amount of use in our country is about 60% of the total amount of stabilizer (excluding lead soap). The thermal stability, electrical insulation and water resistance of dibasic lead stearate are all superior to lead stearate. Commonly used in extruded products, such as pipes, corrugated boards, wires, and also used in injection products. Stabilizer; Lubricant; Rubber product smooth and transparent softener |
| Production method | It is obtained by the reaction of sodium stearate and lead acetate. |
