1.The best substitute of TLS
2.Lead free
3.Use for PVC stabilizer
4.PVC heat stablizer Tribasic lead sulfate
PVC heat stabilizers tribasic lead sulfate (Cas no:12202-17-4) Heat stabilizers for PVC. For opaque rigid PVC pipe, sheet, injection molding products, also used in leather products. Because of its excellent performance, are widely used in PVC electrical insulation materials, can also be used with the paint color, with light stable, the benefits do not change.
Property:
It is white, sweet and toxic powder with the specific gravity of 7.10. It can dissolve in nitric acid, hot thick hydrochloric acid, ammonium acetate and sodium acetate, partly in acetic acid, but not in water. It will turns to yellow when loses the crystal water at 135, it turns to yellow under sunlight, especially in wet condition.
