Calcium stearate CAS:1592-23-0 Product Introduction
Product name: Calcium stearate
Appearance: White light crystalline powder.
Calcium stearate is also known as calcium octadecate. White light crystalline powder. Chemical formula (C17H35COO)2Ca. Molecular weight 607.00. Melting point 179 ~ 180 ℃, decomposed by high heat. Insoluble in water, cold ethanol Chemicalbook and ether, soluble in hot benzene, toluene and turpentine, slightly soluble in hot ethanol and ether. It is decomposed into stearic acid and the corresponding calcium salt with strong acid. Absorbs water in the air. Not resistant to lipolytic microorganisms. Pyrolysis produces stearyl ketone and hydrocarbons. Nontoxic.

Calcium stearate Application:
1.Used as a non-toxic stabilizer, lubricant, mold release agent and textile waterproofing agent for PVC plastics
2.Used as lubricant for coated paper and paint
3.Used as an internal lubricant and non-toxic stabilizer for polyvinyl chloride, and as a mold release agent in the foundry industry Anticaking agent; Binder; Emulsifier; Lubricant; Release agent; Stabilizer; Thickening
agent; Flavoring agent.
4.It is used as a stabilizer and lubricant for polyvinyl chloride, and can be used as non toxic food packaging, medical equipment and other soft film utensils. As a halogen absorber in polyethylene and polypropylene, it can eliminate the residual catalyst in the resin as a lubricant for resin color and molded products, and can also be used as a lubricant for phenolic, amino and other thermosetting plastics and polyester reinforced plastics. agent, thickening agent for grease, waterproofing agent for textiles and flattening agent for paint, etc. Food grade calcium stearate acts as an anticaking agent to prevent powdered or crystalline food from clumping and clumping to keep it free flowing.
5.Used as water repellent, lubricant and plastic auxiliaries. Widely used in food, medicine, cosmetics, plastic rubber and other industries, mainly as lubricants, emulsifiers, stabilizers, release agents, accelerators, cosmetic base materials, etc. In rigid plastic products, the setting speed can be increased. It can also be used for non-toxic soft films such as food packaging and medical equipment, and has the effect of stabilizer, with good long-term stability. It can be used as stabilizer and lubricant in polyethylene and polyvinyl chloride, and as halogen absorber in polyethylene and polypropylene, it can eliminate the adverse effects of the catalyst remaining in the resin on the color and stability of the resin. Widely used in foreign countries to improve the heat resistance of plastics
