Calcium Stearate
Calcium Stearate by Tricon - Smooth Processing, Reliable Performance
Calcium Stearate is a white, fine, hydrophobic powder widely used as a lubricant, stabilizer, and release agent in plastics, rubber, construction materials, and pharmaceutical industries. It is the calcium salt of stearic acid and is valued for its water-repellent properties, excellent thermal stability, and non-toxic profile. Due to its multifunctional characteristics, Calcium Stearate plays an essential role in improving processing efficiency and product performance.
In the plastics industry, Calcium Stearate acts as an internal and external lubricant, reducing friction during extrusion and injection molding. It improves melt flow, prevents sticking to molds, and enhances surface finish. In PVC applications, it is often used as a heat stabilizer, either alone or in combination with zinc stabilizers, helping prevent degradation during high-temperature processing.
In rubber manufacturing, it serves as a mold release agent and processing aid. The compound is also widely used in cement and concrete applications as a waterproofing additive, improving moisture resistance and durability. In pharmaceuticals and cosmetics, Calcium Stearate functions as a flow agent and anti-caking additive in powders and tablets.
Calcium Stearate is chemically stable under normal conditions and should be stored in a cool, dry place to prevent moisture absorption. Its non-toxic and versatile nature makes it suitable for various industrial and regulated applications.
Key Types and Characteristics of Calcium Stearate
Calcium Stearate is available as a fine white powder, granules, or flakes depending on application requirements. Surface-treated grades are also offered to enhance dispersion in polymer and rubber formulations. Powder form is most common for plastics and construction uses, while pharmaceutical-grade variants meet higher purity standards.
Calcium Stearate may be permitted as a food additive or anti-caking agent in certain regions, subject to regulatory approvals. It is used in powdered foods, baking mixes, and supplements to improve flowability and prevent clumping. Usage levels must comply with local food safety regulations.
In pharmaceuticals, Calcium Stearate functions as a tablet lubricant and flow agent, preventing sticking during compression. Industrially, it is used in plastics, rubber, cement, paints, and coatings as a lubricant, stabilizer, and waterproofing additive. It enhances processing efficiency and product durability across applications.
Calcium Stearate may be used in animal feed as an anti-caking agent or processing aid, depending on regulatory permissions. It helps maintain powder flow and prevents lump formation in mineral premixes and feed supplements. Usage must follow approved inclusion limits.
Calcium Stearate appears as a white, odorless powder that is insoluble in water and stable under normal storage conditions. It has hydrophobic characteristics and good thermal stability. It is generally considered safe when handled properly, though dust control measures are recommended during bulk handling.
Calcium Stearate is produced by reacting stearic acid with calcium oxide or calcium hydroxide under controlled heating conditions. The resulting salt is filtered, dried, and milled into the desired particle size. Quality control ensures consistent purity, particle distribution, and performance characteristics.
