Food grade calcium stearate, calcium stearate Chinese name: calcium stearate Chinese alias: eighteen calcium salt English name: Calcium stearate English Name: Stearic acid calcium salt CAS Number: 1592-23-0 Formula: C36H70CaO4 linear formula : [CH3 (CH2) 16COO] 2Ca Molecular Weight: 607.02 EC Number: 216-472-8 Density: 1.08g / cm3 Melting point: 150-155 ℃ calcium content: 6.0-7.0% free acid (stearic acid): ≤ 0.5% Moisture: ≤2.0% Appearance: White powder Solubility: insoluble in water, cold ethanol, soluble in hot benzene, benzene and turpentine and other organic solvents, slightly soluble in hot ethanol. When heated to 400 ℃ decompose slowly, combustible, the case of decomposition of stearic acid and corresponding calcium salt, hygroscopic uses: lubricants for PVC heat stabilizers and a variety of plastics processing, release agents and so on. In rigid products, and the base of the lead salt, lead with soap can increase the gelation rate. Also used in food packaging, medical devices and other requirements of non-toxic soft film and equipment. Can be made of polyethylene, polypropylene, halogen absorbers to eliminate the adverse effects of residual catalyst on the color and stability. As plasticizers in rubber processing, make the whole into a natural rubber and rubber to soften, but almost no effect on the cure. Also used as polyolefin fibers and molded plastic lubricants, grease thickening agent, textile waterproofing agents, paint plain agent, manufacture plastic record when plasticizers. Also used in pencil manufacturing and pharmaceutical, perfume industry. Storage and transportation: sealed in a cool dry place to save. Sales of food grade calcium stearate guide price: 16.1 yuan / kg
