DETAILS
 
 Calcium stearate is in the shape of white powder, insoluble in water, soluble in organic solvents such as hot benzene, benzene and turpentine, slightly soluble in hot ethanol and ether. It decomposes slowly and is flammable when heated to 400 C. It is decomposed into stearic acid and corresponding calcium salt by strong acid and has hygroscopicity. Calcium stearate are widely used as lubricants, slipping agents, heat-stabilizers, mould releasing agents and accelerants in plastic, machinery engineering, rubber, paints and inks industry etc.  

    1.As non-toxic stabilizers and lubricants, mold release agents of polyvinyl chloride and water repellent of textiles. 
    2. As lubricant of coating paper and paint.
    3.As internal lubricant and non-toxic stabilizers of polyvinyl chloride, and as mold release agents of the foundry industry.
    4.Anti-caking agent; adhesive; emulsifier; lubricants; mold release agents; stabilizers; thickeners; flavoring agents.
    5.As stabilizers and lubricants of polyvinyl chloride, and as non-toxic food packaging, medical devices and other soft film containers. As halogen absorbent of polyethylene and polypropylene, it can eliminate residual catalyst in resin. As lubricant of resin colors and molding products, but also as release agents of phenolic, amino thermosetting plastic and plastics and lubricant of polyester reinforced plastic, as thickening agent of grease, waterproofing agents of textile and flatting agent of paint. Food grade Calcium stearate can serve as an anti-caking agent to prevent powdered or crystalline food from aggregation and agglomeration, keeping free-flowing. 
 
Used as waterproofing agent, lubricant and plastic additive.Widely used in food, medicine, cosmetics, plastic and rubber industries, mainly as lubricants, emulsifiers, stabilizers, mold release agents, promoters, cosmetics base materials.Can improve the speed of coagulation in hard plastic products.Can also be used in food packaging, medical equipment and other non-toxic soft film, at the same time with stabilizer effect, long-term stability is good.
