Stearic Acid (CAS 57-11-4), also known as Octadecanoic Acid, is far more than just a cosmetic ingredient; it's a fundamental chemical that underpins numerous industrial processes. As a leading manufacturer and supplier of industrial chemicals, we recognize the critical role Stearic Acid plays in enhancing product performance and streamlining manufacturing operations. Its unique properties as a lubricant, stabilizer, and processing aid make it an indispensable raw material across diverse sectors.

The utility of Stearic Acid in industry stems from its chemical structure and physical characteristics. As a saturated fatty acid, it exhibits excellent lubricating capabilities, acts as a release agent, and helps prevent degradation in polymers and other materials.

Key Industrial Applications:

  • Plastics and Polymers: In the plastics industry, Stearic Acid is widely used as a processing aid and internal/external lubricant for PVC, polyethylene, and other polymers. It improves melt flow, reduces friction during processing, and enhances the surface finish of extruded or molded products. Our industrial-grade Stearic Acid is crucial for manufacturers seeking to optimize their polymer processing.
  • Rubber Industry: Stearic Acid serves as a vulcanization activator and processing aid in the rubber industry. It helps in the dispersion of fillers and accelerators, reduces compound viscosity, and improves the overall mechanical properties of rubber products, including tires. We are a reliable supplier for rubber manufacturers requiring high-quality Stearic Acid.
  • Textiles: Within the textile industry, Stearic Acid is employed in sizing, finishing, and lubrication applications. It imparts smoothness, stiffness, and antistatic properties to yarns and fabrics, improving their handling and performance during manufacturing and in the final product.
  • Lubricants and Greases: The lubricating properties of Stearic Acid and its metal salts (like lithium stearate) make them essential components in various industrial lubricants and greases, reducing friction and wear in machinery.
  • Candle Making: Stearic Acid is a popular additive in candle making. It hardens waxes, increases opacity, and improves the burn time and fragrance throw of candles, especially pillar and votive types.
  • Metalworking: It acts as a lubricant and mold release agent in metal forming, stamping, and casting processes, facilitating smoother operations and better part ejection.
