 Molecular formula: Pb(C17H35COO)2
Property: It is slight white powder with specific gravity 1.323. It can slight dissolved in ethanol ans aether, but not in water. It will become to glue after cooled when being heated in the organic solvent, but to stearate when the decomposed in strong acid and can absorb moisture in air.
Application : As the high efficiency stabilizer and lubricant in low temperature processing, it has good light stability and primary stainability control, so that it could be used widely in the rigid PVC products extrusion and injection.
Package: Plastic weaved bag, lined with PE bag, and 20KG weight.
