Food grade calcium carbonate

　　GCC heavy calcium carbonate

　　Heavy calcium carbonate English name Ground calcium carbonate, molecular formula CaCo3. Heavy calcium carbonate is generally decomposed from calcite. It has high chemical purity, large inertness, difficult chemical reaction, good thermal stability, no decomposition below 400 °C, high whiteness, low oil absorption, low refractive index, and soft texture. Dry, no crystal water, low hardness, low wear value, non-toxic, odorless, odorless, good dispersion and so on. It is widely used as a filler in a wide range of applications such as artificial floor tiles, rubber, plastics, paper, paint, paint, etc., which has increased product volume, reduced cost, and improved processing properties (such as viscosity adjustment, rheological properties, vulcanization properties). Improve dimensional stability, reinforcement or semi-reinforcement, improve printing performance, and improve physical properties (such as heat resistance, matting, abrasion resistance, flame retardancy, whiteness, gloss) and other properties.
