Lead stearate dibasic is a white powder, insoluble in water, soluble in hot ethanol, benzene and turpentine. It is heated and dissolved in an organic solvent and cooled to form a gel. It is decomposed into stearic acid and the corresponding salt in the presence of strong acid, and is hygroscopic. This product is toxic and susceptible to sulfide contamination. Do not dissolve in water, soluble in hot ethanol. Melting point 103-110 ° C

Lead stearate can be used as a heat stabilizer and lubricant for polyvinyl chloride with good lubricity and photothermal stability. It has good synergistic effect with cadmium soap, barium soap or organotin compound. It can be used in various opaque hard and soft PVC products, such as hard tube, hard board, sheet, film and artificial leather, especially suitable for electric wire. Cable material can give the product excellent electrical properties.

This product is toxic, susceptible to sulfide contamination, easy to spray when used in large quantities, and the lead chloride formed during the process of reaction with hydrogen chloride in the resin will affect the transparency of the product. This product can also be used as paint drier and flat light agent and grease thickener, such as PVC 70 ° C sheath grade cable material, 90 ° C and 105 ° C cable material, PVC pipe, pipe fittings, shaped Tube, hard board, shoe material, etc. Because this product is insoluble in water, it can also be used in the formulation of rigid PVC drinking water pipes.

Used as a defoamer for lubricating and decarburizing agents and drilling fluids in oilfield chemicals. It is also used as a paint anti-precipitant, fabric water repellent, lubricating oil thickener, plastic heat stabilizer, etc., as a stabilizer for opaque soft and rigid polyvinyl chloride products.
