Ground Calcium Carbonate (GCC) Powder - Industrial Grade 1. Product Overview Ground Calcium Carbonate (GCC) is a naturally occurring mineral obtained from high-purity limestone or marble. It is mechanically ground into fine powder without changing its chemical structure. GCC is widely used in various industrial applications due to its excellent physical and chemical properties. 2. Chemical & Physical Properties Chemical Formula: CaCO Purity: Typically & 98% Color: White to off-white Particle Size: Available in different micron sizes (5 µm to 50 µm or more) Specific Gravity: ~2.7 g/cm Bulk Density: 0.8 - 1.2 g/cm (varies with fineness) Moisture Content: 0.2% pH: ~8-9 Oil Absorption: Low 3. Industrial Applications Plastics & Polymers Used as a filler to improve mechanical properties and reduce costs in PVC pipes, cables, and plastic films. Paints & Coatings Enhances opacity, brightness, and weather resistance in paints, coatings, and adhesives. Paper Industry Used as a filler to improve paper brightness, smoothness, and printability. Rubber Industry Increases strength, durability, and elasticity in rubber products like tires, belts, and hoses. Construction & Cement Improves strength and workability in cement, concrete, and adhesives. Ceramics & Glass Acts as a fluxing agent to enhance durability and shine in ceramic and glass manufacturing. Pharmaceuticals & Food (if food-grade GCC) Used as a calcium supplement and anti-caking agent in tablets, toothpaste, and food products. 4.
