Use：: Zinc stearate is white light fine powder. Formula is ZN (C17H35COO) 2, molecular structure is RCOOZnOOCR (R is alkyl group of industry stearate), it is combustible, specific gravity is 1.095, ignition point is 900℃, density is 1.095, melting point is 130℃, it has creamy feel. It is insoluble in water, alcohol, ether, soluble in hot ethanol, turpentine, benzene and other organic solvents and acids. Zinc stearate is heated and dissolved in organic solvent, when exposes cold, it becomes jelly, when meets strong acid, it can decompose into stearic acid and corresponding zinc. It has lubricity, hygroscopic, non-toxic, slightly irritating, non-polluting, non-hazardous properties. For zinc stearate is dissolved in benzene and calcium stearate is benzene-insoluble, it is possible to separate the calcium stearate and zinc stearate. Zinc stearate is not soluble in polar solvents, but when be heated, it is high dissolved in aromatic compound agent chlorinated hydrocarbons. The main application areas are plastics and rubber industry, it is used as lubricant and release agent for excellent compatibility.
