Zinc Stearate

General Properties:

• Molecular Formula: Zn(C₁₈H₃₅O₂)₂

• Appearance: Fine white hydrophobic powder

• Melting Point:               ~120–130°C

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

...

Applications:

• Plastics & Polymers

  • Used as an internal and external lubricant in PVC, polyolefins, and engineering plastics to improve melt flow, prevent sticking, and enhance surface quality.

• Rubber Manufacturing

  • Improves dispersion of fillers, reduces adhesion to metal surfaces, and enhances processing efficiency in rubber compounding.

• Powder Coatings & Paints

  • Acts as a flow and leveling agent, improving powder dispersion, surface smoothness, and anti-caking performance.

• Cosmetics & Personal Care

  • Used in select formulations as a texture enhancer and flow agent, contributing to smooth application and moisture resistance.

• Powder Metallurgy

  • Functions as a lubricant and binder to improve mold release, compaction, and part uniformity.

...

Advantages:

• Excellent Mold Release Performance: Reduces sticking and surface defects, enabling smoother production and higher-quality finished products.

• Enhanced Lubricity & Processing Efficiency: Minimizes friction and wear, allowing faster processing and improved equipment performance.

• Superior Hydrophobic Properties: Provides moisture resistance and anti-caking benefits in powders and coatings.

• Thermal Stability: Performs reliably under high-temperature processing conditions common in plastics and rubber manufacturing.

• Broad Industry Versatility: A single additive delivering lubrication, release, and flow control across multiple industries.

...

Safety & Handling:

Zinc Stearate is generally considered low hazard when handled properly but should be managed using standard industrial safety practices.

• Dust may cause mild eye, skin, or respiratory irritation

• Avoid inhalation of airborne powder

• Non-flammable, but fine dust may create nuisance conditions
