Calcium Stearate

General Properties:

• Molecular Formula: Ca(C₁₈H₃₅O₂)₂

• Appearance: Fine white powder

• Solubility: Insoluble in water; soluble in some organic solvents

• Key Functions: Lubricant, release agent, anti-caking agent, water repellent

Applications:

• Plastics & Polymer Processing

  • Used as a lubricant and stabilizer in PVC and polyolefins to improve flow, reduce friction, and enhance processing efficiency.

• Rubber Manufacturing

  • Improves mold release, prevents sticking, and enhances dispersion of fillers during compounding.

• Construction Materials

  • Acts as a water-repellent additive in cement, concrete, and plaster, improving durability and workability.

• Powder Processing & Chemicals

  • Functions as an anti-caking agent and flow aid in powders, pigments, and specialty chemical blends.

• Coatings & Industrial Formulations

  • Enhances dispersion, surface finish, and moisture resistance in coatings and specialty applications.

Advantages:

• Improves Processing Efficiency: Reduces friction and sticking, enabling smoother production and higher throughput.

• Excellent Water Repellency: Provides hydrophobic properties that improve product durability and shelf life.

• Multi-Functional Performance: Combines lubrication, stabilization, and anti-caking benefits in a single additive.

• Thermal Stability: Performs reliably under elevated temperatures typical of polymer and rubber processing.

Safety & Handling:

Calcium Stearate is generally considered low hazard but should be handled using standard industrial safety practices.

• May cause mild irritation to eyes, skin, or respiratory tract due to dust

• Avoid inhalation of airborne particles
