Introduction：

Barium stearate is also known as "barium octadecate", with the chemical formula Ba(C18H35O2)2. Molecular weight 704.13. White fine powder. The melting point is 160°C, and the relative density is 1.15. Insoluble in water, insoluble in cold ethanol, soluble in hot ethanol, benzene, toluene and other non-polar solvents, heated and dissolved in an organic solvent and turned into a gel after cooling. In case of strong acid, it is decomposed into stearic acid and the corresponding barium salt. Absorbs water in the air. Preparation method: It is prepared by reacting stearic acid with barium carbonate or barium hydroxide, or by reacting sodium stearate solution with dilute barium chloride solution. It can be used as waterproof product, filler of alkali pump, high temperature resistant lubricant and filler of machine; light resistant and heat resistant stabilizer of PVC and other plastics, high temperature resistant powder mold agent of rubber products, etc. Barium stearate is toxic, with a toxicity coefficient of T=2. Typical symptoms of poisoning are vomiting, abdominal pain, diarrhea, increased blood pressure, and pulse disturbance.

White crystal powder. Insoluble in water and ethanol.

●  Used as high temperature resistant lubricant for machines, high temperature resistant auxiliary agent for rubber products, light resistant and heat resistant stabilizer for PVC plastics

●  Used as heat stabilizer for PVC products

●  Used as water repellent, lubricant and bearing packing

●  It is used as high temperature resistant lubricant for machinery and high temperature resistant powder for rubber products. It can be used as stabilizer and lubricant for polyvinyl chloride. Among all alkaline earth metal stearate, this product has the best long-term heat resistance. Mainly used for soft transparent film, sheet, artificial leather and hard plate, tube, etc. It can also be used as a high temperature resistant mold release agent and a high temperature lubricant for machinery.
