Calcium Stearate is a widely used additive known for its lubricating and stabilizing properties. As a calcium-based salt of stearic acid, it appears as a white, powdery substance that is insoluble in water but highly effective in reducing friction, enhancing material processing, and providing moisture resistance in various industrial applications. From plastics manufacturing to pharmaceuticals, Calcium Stearate plays a crucial role in improving product quality and efficiency.Get more news about Calcium Stearate,you can vist our website!
Composition and Properties
Chemically, Calcium Stearate is a metal soap composed of calcium and stearate ions. It is non-toxic, environmentally safe, and possesses hydrophobic properties, making it resistant to water absorption. It has a low melting point, allowing for easy blending with other materials, and functions effectively as a lubricant and mold-release agent in high-temperature processes.
Applications in Industry
Plastics and Rubber
In the plastic industry, Calcium Stearate is used as a processing aid and internal lubricant. It helps improve dispersion during molding, reduces wear on machinery, and enhances the durability of finished plastic products. Similarly, in rubber manufacturing, it prevents adhesion between surfaces and enhances flexibility.
Construction and Cement Industry
Calcium Stearate serves as a waterproofing agent in construction materials. It is commonly added to concrete and cement to improve moisture resistance and prevent degradation caused by environmental factors.
Pharmaceuticals and Cosmetics
Due to its non-toxic nature, Calcium Stearate is widely used in the pharmaceutical industry as a tablet-coating agent. It helps in the smooth processing of medicines and ensures uniform tablet formation. In cosmetics, it is incorporated into skincare and makeup products to improve texture and stability.
Paper and Coatings
In paper production, Calcium Stearate acts as an anti-blocking agent, improving paper smoothness and reducing friction. It is also used in coatings and paints to enhance dispersion and provide anti-caking properties.
