1.Stearic Acid Modified Talc Powder is treated with stearic acid to improve compatibility with polymers, enhancing dispersion and reducing hydrophilicity. 2.Stearic Acid Modified Talc PowderImproves mechanical properties (e.g., tensile strength, impact resistance) in plastics, rubber, and coatings by reducing filler agglomeration. 3.Stearic Acid Modified Talc Powder coating makes talc water-repellent, beneficial for moisture-sensitive applications like cables and outdoor materials. 4.Stearic Acid Modified Talc Powder Reduces viscosity in polymer melts, improving flow during injection molding or extrusion. 5.Stearic Acid Modified Talc Powder Used in automotive parts, PP/PE composites, paints, and adhesives where interfacial bonding is critical.

Stearic Acid Modified Talc Powder is a surface-treated form of talc powder, where stearic acid is used as a coupling agent to improve compatibility with organic matrices (such as polymers). This modification enhances Special function grade talc powder's dispersion, adhesion, and performance in composite materials.


Key Features:

1.Surface Hydrophobicity – Special function grade talc powder, making them hydrophobic (water-repellent) and improving compatibility with non-polar polymers like PP, PE, and PVC.

2.Improved Dispersion – Special function grade talc powder Reduces particle agglomeration, ensuring uniform distribution in polymer matrices.

3.Enhanced Mechanical Properties – Special function grade talc powder Increases tensile strength, stiffness, and impact resistance in composites.

4.Better Processing – Reduces viscosity in molten polymers, improving flow during extrusion or injection molding.

5.Thermal Stability – Maintains talc's inherent heat resistance while improving interfacial bonding.


Applications:

  • Plastics & Polymers – Talc powder chemical for formula Used in polypropylene (PP), polyethylene (PE), PVC, and engineering plastics for automotive parts, packaging, and household goods.

  • Rubber Industry – Talc powder chemical for formula Enhances reinforcement and processing in tires, seals, and gaskets.

  • Coatings & Paints – Talc powder chemical for formula Improves scratch resistance and durability.

  • Cosmetics – Talc powder chemical for formula Acts as a filler in powders and foundations for smooth texture.


Modification Process:

1.Dry Method – Talc powder is mixed with stearic acid in a high-speed mixer at elevated temperatures (~100–120°C).

2.Wet Method – Stearic acid is dissolved in a solvent, mixed with talc, then dried and ground.


Advantages Over Unmodified Talc:

  • Better polymer adhesion

  • Reduced moisture absorption

  • Higher mechanical strength in composites

  • Smoother processing in extrusion/molding


Typical Specifications:

  • Particle Size: 1–20 µm (depending on grade)

  • Stearic Acid Content: 0.5–2% by weight

  • Moisture Content: <0.5%
