产品描述
Calcium stearate White powder, insoluble in water, cold ethanol and ether, soluble in organic solvents such as hot benzene, benzene and turpentine, slightly soluble in hot ethanol and ether. When heated to 400ºC, slowly decomposed, flammable, in case of strong acid decomposition into stearic acid and the corresponding calcium salt, moisture absorption.
特征
Calcium stearate is also called calcium stearate. White light crystalline powder. Chemical formula (C17H35COO)2Ca. Molecular weight 607.00. Melting point 179 ~ 180℃, subject to high thermal decomposition. Insoluble in water, cold ethanol Chemicalbook and ether, soluble in hot benzene, toluene and turpentine, slightly soluble in hot ethanol and ether. Decompose with strong acid into stearic acid and corresponding calcium salt. It absorbs water in the air. Lipophilic intolerant microorganism. High temperature decomposition to produce stearone and hydrocarbon. Non-toxic.
应用
- 1.Used as a non-toxic heat stabilizer for polyvinyl chloride, and has excellent lubricity. The heat stabilization effect is not as good as barium stearate, lead stearate, tin stearate and cadmium stearate. But cheap and easy to obtain, little toxicity, good processing performance. It has synergistic effect with zinc soap and epoxy compound and can improve thermal stability. Commonly used in food packaging film, medical equipment and other non-toxic soft products. With basic lead salt and lead soap and used in hard products, the gelation rate can be improved. This product is used in polyethylene and polypropylene to eliminate the adverse effects of residual catalysts on the color and stability of the resin.
- 2.Used as a lubrication release agent in oil field operations. Also used as polyvinyl chloride heat stabilizer and a variety of plastic processing lubricants, release agents and so on. In hard products, the gelation rate can be improved by combining with basic lead salt and lead soap. Also used in food packaging, medical equipment and other requirements of non-toxic soft film and equipment. It can also be used as a halogen absorber for polyethylene and polypropylene to eliminate the adverse effects of residual catalysts on color and stability. As a plasticizer in rubber processing, it can soften natural rubber and synthetic rubber, and it has almost no effect on vulcanization. It is also used as a thickening agent for greases, a waterproofing agent for textiles, a smoothing agent for paints, and a plasticizer for making plastic records.
- 3.Calcium stearate is a good non-toxic heat stabilizer and lubricant, but also a smooth agent and water resistant agent of adhesives, coatings, widely used in plastics and rubber and other chemical production processes. The heat stabilization effect is not as good as barium stearate, lead stearate, tin stearate and cadmium stearate. But cheap and easy to obtain, little toxicity, good processing performance. It has synergistic effect with zinc soap and epoxy compound and can improve thermal stability. Commonly used in food packaging film, medical equipment and other non-toxic soft products. It is also widely used as a lubricant and release agent for thermosetting plastics such as polyolefin, polyester reinforced plastics, phenolic resins and amino resins.
- 4.Used in perfume powder in cosmetics. When added to the powder, it has strong adhesion to the powder, good lubricity, uniform spreading and good formability of the powder.
