Vietnam Calcium Carbonate
Coated CaCO3 — Active Series Grade
Our Premium Vietnam Coated Calcium Carbonate is surface-modified with high-quality Stearic Acid to maximize its efficiency as a functional filler.
Featuring exceptional hydrophobic properties, reduced oil absorption, and stellar dispersion capabilities, this active series grade blends smoothly with a wide variety of polymer matrix operations, improving mechanical properties and cost efficiencies.
Key Features
- Surface-treated with premium Stearic Acid for full hydrophobicity
- Ultra-fine particle size for smooth, high-speed processing
- High whiteness (≥98%) and brightness (≥96%)
- Excellent dispersion in PP, PE & PVC polymer systems
- Reduced oil absorption versus uncoated grades
- Consistent, batch-to-batch reliable specifications
