Introduction To Lead Stearate
Oct 09, 2018

Lead Stearate is a white powder, insoluble in water, soluble in hot ethanol, benzene and turpentine, in the organic solvent heated dissolved and cooled into a gel, when the acid decomposition into stearic acid and the corresponding salt, there is hygroscopic. Lead stearate can be used as a heat stabilizer and lubricant for polyvinyl chloride, which has good lubricity and Light-heat Stability. With cadmium soap, barium soap or organotin compound with good synergistic effect, can be used in a variety of opaque hard and soft PVC products, such as hard tube, rigid board, sheet, film and artificial leather, especially suitable for wire and cable material, can give excellent electrical properties of Products. however, This product is toxic, susceptible to sulfide pollution, the use of large amount of easy to spray, and in the process of processing and the reaction of hydrogen chloride in the resin produced lead chloride, will affect the transparency of the Product. This product can also be used as a paint drier and grease thickening agent, such as PVC 70 ℃ sheath Grade cable material, 90 ℃ and 105 ℃ cable material, PVC pipe, pipe fittings, special-shaped tube, rigid board, shoe material and so On. Because this product is insoluble in water, it can also be used in the formulation of rigid polyvinyl chloride drinking water pipe. In addition, it can be used as a defoaming agent for lubricating and drilling fluid in oilfield chemicals.

Also used as paint anti-settling agent, fabric release agent, lubricating oil thickening agent, plastic heat stabilizer, etc., for the non-transparent soft and rigid PVC products Stabilizer.
