Vietnamese vs Indian Calcium Carbonate Powder: Technical Comparison & Selection Guide
Overview of Calcium Carbonate Demand in India
The Indian plastic, paint, and ceramics industries are growing rapidly, creating a high demand for quality calcium carbonate (CaCO₃) powder. Selecting the right powder is crucial to:
Improve product performance and finish
Reduce production defects
Optimize production costs
Plastic Industry: CaCO₃ acts as a filler in PVC, PP, and PE, enhancing rigidity, surface finish, and cost-efficiency.
Paint Industry: Used for opacity, whiteness, and smooth texture. Coated CaCO₃ ensures better dispersibility.
Ceramics & Tiles: Improves thermal stability, reduces cracking, and enhances surface quality.
Vietnamese vs Indian Calcium Carbonate Powder
Choosing between Vietnamese and Indian CaCO₃ powder depends on purity, particle size, whiteness, coating, and price.
Quality Comparison
| Parameter | Vietnam CaCO₃ | India CaCO₃ |
|---|---|---|
| Purity (CaCO₃) | ≥ 98% | 95–97% |
| Whiteness | 97–99% | 92–96% |
| Particle Size (Mesh) | 400–2500 | 200–2000 |
| Moisture | ≤ 0.3% | ≤ 0.5% |
| Price | Competitive | Medium |
Coated vs Uncoated CaCO₃
Coated: chemically treated, excellent dispersibility, suitable for premium paints and PVC. Prevents clumping.
Uncoated: cost-effective for standard applications but may require extra dispersion agents.
Applications in Different Industries
– Plastic Industry
PVC pipes & profiles: Requires fine particle size (400–800 mesh) and low oil absorption.
PP & PE products: Uniform dispersion ensures mechanical strength and surface finish.
Masterbatch: Stabilizes color and improves rigidity; coated CaCO₃ recommended.
– Paint Industry
Enhances whiteness, opacity, and smooth finish.
Coated CaCO₃ reduces viscosity and improves spreadability.
Helps reduce paint consumption without compromising coverage.
– Ceramics & Tiles
Uniform particle size ensures better thermal stability.
Reduces cracking during firing and improves surface smoothness.
Vietnamese CaCO₃ often preferred due to higher purity and lower impurity content.
Cost Optimization & Production Efficiency
Proper selection of calcium carbonate powder can significantly reduce production costs while maintaining quality.
Filler ratio: 20–40% by weight depending on application
Vietnamese CaCO₃: high whiteness reduces need for additional pigments
Uniform particle size minimizes processing issues (clumping, uneven mixing)
Testing small batches before bulk purchase ensures proper fit with machinery
Common Issues & Solutions
| Issue | Cause | Solution |
|---|---|---|
| Clumping in paint | Moisture / uncoated powder | Use coated CaCO₃, proper storage |
| Non-uniform texture in plastic | Uneven particle size | Choose micronized powder |
| Reduced whiteness | Low purity | Select high-purity Vietnamese powder |
| Equipment wear | Abrasive particles | Ensure quality control and particle size grading |
