Light Calcium Carbonate (Precipitated Calcium Carbonate, PCC)
800-2000 mesh plastic-specific fillers with moisture content ≤0.3%
Material Profile
Light Calcium Carbonate is a synthetic, fine, white powder produced through chemical precipitation, characterized by its high purity, specific particle morphology, and low density. It serves as a versatile functional filler and additive across numerous industries, valued for its ability to enhance product properties while reducing costs.
Core Characteristics
- Chemical Nature: Alkaline, reacts with strong acids
- Particle Morphology: Controlled shapes (cubic, rhombohedral, scalenohedral, spherical)
- Surface Chemistry: Polar, hydrophilic (can be modified to hydrophobic)
- Key Differentiator vs. Ground Calcium Carbonate (GCC): Higher purity, narrower particle size distribution, engineered particle shape
