Characteristics: 

Lead stearate is a white powder, insoluble in water, but soluble in hot ethanol, benzene and turpentine.

When heated in organic solvents, lead stearate dissolves into a jelly after cooling.

When met with strong acid, lead stearate is decomposed into stearic acid and the corresponding salt.

 

 

Applications: 

Lead stearate can be used as heat stabilizer and lubricant of PVC.
