![]() The heat stabilizer and the colorant are mainly used for opaque polyvinyl chloride hard pipes, plates, injection molding products, rubber and artificial leather products and the like due to its excellent insulating properties, it is widely used for electrical insulating materials of polyvinyl chloride because it has the advantages of stability to light and no discoloration, and can be used for coloring paint. The tribasic lead sulfate is an important chemical raw material, has a stabilizing effect on polyvinyl chloride, has excellent heat resistance and electrical insulation, has good light resistance, and is particularly suitable for high-temperature processing. H 2O) is white or slightly reddish or slightly yellowish powder, has a specific gravity of 7.10, a melting point of 820 ℃, is sweet, toxic, easy to absorb moisture, non-combustible and insoluble in H 2O and CH 3CH 2OH, but dissolved in acid and hot ammonium acetate solution, changes color when wet and decomposes itself.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
