Descrizione del prodotto
Calcium Carbonate Powder - Filler for Plastics & Paints, Food Additive E170, Dietary Supplement
Calcium carbonate (CaCO₃) is one of the most abundant natural minerals on Earth, serving as a vital inorganic filler and functional material. Available as Ground Calcium Carbonate (GCC) milled from minerals like calcite and Precipitated Calcium Carbonate (PCC) produced chemically, this white fine powder offers exceptional properties including high whiteness, low hardness, chemical inertness, cost-effectiveness, and calcium source functionality.
Core Applications and Industry Uses
Reinforcing Filler for Plastics and Rubber
As the most widely used inorganic filler in plastic products (PVC profiles, pipes, PE, PP), calcium carbonate increases product volume, reduces material costs, improves dimensional stability, and enhances impact resistance. Through precise particle size control and surface treatments like stearate coating, it provides reinforcement, toughening, and improved processing flowability. In rubber applications (tires, hoses, shoe soles), it serves as a semi-reinforcing or extender filler to modify compound properties while reducing costs.
Performance Modulator for Paper and Coatings
In paper manufacturing, calcium carbonate functions as both filler and coating pigment, increasing opacity, smoothness, and printability while significantly lowering production costs. As a core raw material for high-quality coated paper and art paper, it delivers excellent gloss and superior print results. In paints and coatings (latex paints, industrial coatings), it increases film build, improves hiding power, enhances leveling, adjusts sheen for matting effects, and reduces costs. Nano-sized calcium carbonate provides additional reinforcement and anti-aging benefits.
Safe Nutritional Source for Food and Pharmaceuticals
Food-grade calcium carbonate (E170) serves as a nutritional fortifier (calcium source), anti-caking agent, acidity regulator, and leavening agent in products including flour, breakfast cereals, milk powder, fruit juice, and chewing gum. It provides safe, non-toxic dietary calcium supplementation. In pharmaceuticals, it functions as an antacid to neutralize gastric acid and as a calcium source in tablets and powders for osteoporosis prevention and treatment.
Foundation Material for Building and Environmental Applications
As a primary raw material for cement, lime, and artificial marble production, calcium carbonate also serves as a filler in joint compounds and sealants. Environmental applications include Flue Gas Desulfurization (FGD) to react with sulfur dioxide producing gypsum, wastewater treatment to neutralize acidic effluent and precipitate heavy metal ions, and soil amendment to adjust pH levels in acidic soils. Additionally, it functions as a mineral feed supplement to provide essential calcium for livestock and poultry bone development.
