Calcium stearate

Chinese name: calcium stearate. English name: Calcium stearate. CAS: 1592-23-0. Formula: C36H70CaO4. Linear formula: [CH3 (CH2) 16COO] 2Ca. Molecular Weight: 607.02 Properties: white powder. Density 1.08g / cm3. Melting point 158 ??℃, insoluble in water, slightly soluble in hot ethanol, the case of decomposition of stearic acid and corresponding calcium salt. With water absorption in the air, non-toxic. Usage: Dehydrated vegetables to do anti-caking agents, emulsifiers and the like, such as spices and the like. For PVC heat stabilizers and a variety of plastics processing lubricants, release agents and the like. In rigid products, and the base of the lead salt, lead with soap can increase the gelation rate. Also used in food packaging, medical equipment and other requirements of non-toxic flexible film and apparatus. It can be made of polyethylene, polypropylene, halogen absorbent to remove the adverse effects of residual catalyst on the color and stability. As plasticizers in rubber processing, make the whole natural rubber and synthetic rubber to soften, but almost no effect on the vulcanization. Also used as the polyolefin fibers and molded plastic lubricants, grease thickening agent, textile waterproofing agents, paint the plain agent during the manufacture of plastic labels plasticizers. Also used in pencil manufacturing and pharmaceutical, perfume industry. Physical characteristics: calcium content: 6.5 ± 0.6% Free acid (stearic acid) ≤0.5% Heating loss ≤3.0% Melting point ≥140 ℃ Fineness (0.075mm sieve through) ≥99.0%.
