Product Description:
Calcium stearate is a white, fine - powdered solid with a faint, characteristic odor. It is a metallic soap, formed by the reaction of stearic acid and calcium hydroxide. Insoluble in water, but soluble in organic solvents like benzene and chloroform, it has a relatively high melting point. In the plastics industry, calcium stearate is widely used as a lubricant and stabilizer. As a lubricant, it reduces friction during the processing of plastics, facilitating the extrusion and injection - molding processes. As a stabilizer, it helps to prevent degradation of plastics caused by heat and light, thus extending the lifespan of plastic products. In the rubber industry, it serves as a release agent, enabling easy separation of rubber products from molds. In the paint and coatings industry, it functions as a thickening agent and a drier. It can adjust the viscosity of paints, ensuring smooth application, and also promotes the drying process. In the food industry, it is used as an anticaking agent in powdered foods, preventing clumping and maintaining the free - flowing nature of the product. In the pharmaceutical industry, it can be used as a tablet lubricant, ensuring smooth tablet formation during manufacturing. However, when handling calcium stearate, it is important to avoid creating dust clouds, as inhalation of the powder may cause respiratory discomfort. Also, proper storage in a cool, dry place is necessary to maintain its quality.

 

Application: 

Calcium stearate has various applications. In plastics, it acts as a lubricant for easier processing and a stabilizer against heat and light degradation. In rubber, it serves as a release agent for mold separation. In paint, it thickens the formulation and speeds up drying. In food, it functions as an anticaking agent for powdered products. In pharma, it's used as a tablet lubricant for smooth manufacturing. However, when handling, be cautious of dust inhalation, and store it in a cool, dry place.
