Description:
White powder, insoluble in water, soluble in hot ethanol, benzene
and turpentine. It is heated and dissolved in an organic solvent to
form a gel after cooling. It is decomposed into stearic acid and
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 ******0 ° C
Usage:
1. 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.
2. Used as a defoaming agent 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.
