Zinc Stearate
Zinc Stearate by Tricon - Smooth Processing, Superior Performance
Zinc Stearate is a fine, white, hydrophobic powder widely used as a lubricant, release agent, and stabilizer in various industrial applications. It is the zinc salt of stearic acid and is valued for its excellent water-repellent properties, thermal stability, and non-toxic profile. Due to its multifunctional performance, Zinc Stearate plays a critical role in plastics, rubber, coatings, cosmetics, and pharmaceutical manufacturing.
In the plastics industry, Zinc Stearate acts as an internal and external lubricant, improving melt flow during extrusion and injection molding. It prevents materials from sticking to molds and processing equipment, ensuring smooth surface finishes and enhanced production efficiency. In rubber processing, it functions as a release agent and activator in sulfur vulcanization systems.
Zinc Stearate is also widely used in powder metallurgy, paints, and coatings, where it enhances texture, dispersion, and anti-caking performance. In cosmetics, it serves as a thickening and lubricating agent in face powders and ointments. Its non-reactive and stable nature makes it suitable for pharmaceutical tablet manufacturing as a glidant and lubricant.
The product is chemically stable under normal conditions and safe when handled according to industrial guidelines. It should be stored in a cool, dry place to prevent moisture absorption and contamination.
Key Types and Characteristics of Zinc Stearate
Zinc Stearate is typically available as a fine white powder or granulated form for industrial applications. It is supplied in coated and uncoated grades depending on processing requirements. Special surface-treated grades are also available for improved dispersion in plastics and rubber compounding systems.
Zinc Stearate is not commonly used directly in food products but may be permitted in certain processing aids depending on regional regulations. It is generally recognized for indirect food contact applications, such as in food packaging materials and processing equipment where lubrication and release properties are required.
In pharmaceuticals, Zinc Stearate functions as a tablet lubricant and glidant to improve powder flow and prevent sticking during compression. Industrially, it serves as a mold release agent, lubricant, stabilizer, and anti-blocking additive in plastics, rubber, coatings, and powder metallurgy processes.
Zinc Stearate has limited direct use in animal feed formulations. However, zinc compounds may contribute to mineral supplementation in regulated forms. Its primary relevance is indirect, particularly in feed packaging and processing systems where it acts as a lubricant or release agent in manufacturing equipment.
Zinc Stearate appears as a white, fine, hydrophobic powder with a slight fatty odor. It is insoluble in water but soluble in aromatic hydrocarbons when heated. It is chemically stable and non-toxic under normal handling conditions. Dust generation should be minimized, and protective equipment is recommended during bulk handling.
Zinc Stearate is produced by reacting stearic acid with zinc oxide or zinc salts under controlled temperature conditions. The reaction forms the zinc salt, which is then filtered, dried, and milled into fine powder. Surface treatment processes may be applied to enhance dispersion and performance characteristics.
