Zinc Stearate, a chemical compound derived from stearic acid and zinc ions, is widely used in various industries. It typically appears as a fine white powder. Its main characteristics include purity, particle size, and physical appearance, usually as a soft powder.

Key Functions of Zinc Stearate
• Lubricant: Reduces friction between surfaces during thermal processes such as extrusion, injection molding, and compression—especially in plastic and rubber production.
• Mold Release Agent: Prevents polymers or resins from sticking to molds, reduces mold wear, and improves the surface quality of final parts.
• Formulation Stabilizer: Provides uniformity in complex systems such as masterbatch, pigments, coatings, and polymer additives.
• Anti-abrasion Modifier: Reduces scratching and surface wear while improving durability in industrial paints, powder coatings, and printing inks.

Industrial Applications of Zinc Stearate

1. Polymer and plastic industries – as an internal and external lubricant in PVC, PP, and PE
2. Rubber and foam industry – in EVA compounds and natural/synthetic rubber
3. Paints, lacquers, and powder coatings – to improve mechanical properties and processability
4. Masterbatch and pigments – as a dispersing agent and formulation stabilizer
5. Shoe production, molded parts, and composites manufacturing

Advantages of Zinc Stearate
• Low volatility and high thermal stability
• Compatibility with various polymers and chemical compounds
• Increases mold lifespan and reduces sticking
• Effective performance even at low dosages
