Industry Applications

 

1. Plastics & Polymers

• Function: Filler (20-40% load), improves stiffness & heat resistance

• Uses: PVC pipes, profiles, PP woven bags, masterbatch
   

2. Paints & Coatings

• Function: Extender pigment, enhances opacity & weather resistance

• Uses: Water-based paints, primers, powder coatings
   

3. Rubber Industry

• Function: Reinforcing agent, reduces cost vs. carbon black

• Uses: Tire sidewalls, shoe soles, rubber hoses
   

4. Construction Materials

• Function: Cement additive (5-15%), improves workability

• Uses: Tile adhesives, self-leveling compounds, drywall
   

5. Paper Industry

• Function: Coating pigment (GCC), improves printability

• Uses: High-gloss paper, packaging board
   

6. Other Uses

• Adhesives: Thixotropic agent

• Animal Feed: Calcium supplement

• Environmental: Flue gas desulfurization (FGD)

Critical Precautions

 

• Storage:

  • Keep in dry, sealed containers (RH <60%) to prevent caking.

  • Avoid contact with acids (releases CO2 gas).
     

• Handling:

  • Wear dust masks (for fine powders) and goggles.

  • Use anti-static equipment for bulk loading (dust explosion risk).
     

• Compatibility:

  • Not suitable for acidic environments (pH <5).

  • Test heat stability if used in plastics >200°C.
