Description

Cadmium Stearate is a metallic soap of stearic acid, widely utilized as a heat and light stabilizer and lubricant in polymer processing. Its primary commercial value lies in its ability to impart excellent thermal stability and clarity to finished products, particularly in PVC applications. This compound is essential for manufacturers in the plastics, rubber, and coatings industries seeking to enhance product durability and processing efficiency.

Application

• Primary heat stabilizer and lubricant for polyvinyl chloride (PVC) and other halogenated polymers.
• Used as a mold release agent and internal lubricant in plastic and rubber compounding.
• Acts as a waterproofing agent and hydrophobizing agent in textiles and construction materials.
• Functions as a flatting agent (matting agent) in paints, varnishes, and lacquers.
• Employed as a catalyst or reaction intermediate in certain organic syntheses.
• Serves as a cosmetic grade ingredient in specific formulations, subject to purity and regulatory compliance.
