Metallic Stearates: Properties, Uses, and Industrial Importance
Metallic stearates are metal salts of stearic acid, a long-chain fatty acid derived from natural fats and oils. These compounds combine the properties of both metal ions and fatty acids, giving them unique characteristics such as lubrication, water repellency, and heat stability. Because of these qualities, metallic stearates are widely used in plastics, rubber, pharmaceuticals, cosmetics, and many other industries.
What Are Metallic Stearates
Metallic stearates are formed when stearic acid reacts with metal compounds such as calcium, zinc, magnesium, aluminum, or sodium. The resulting powders or flakes are hydrophobic, heat resistant, and easily dispersible, making them versatile industrial additives.
Common Types of Metallic Stearates
Calcium StearateWidely used in plastics and rubber processing for lubrication and release properties.
