Product Description
Chemical name: Calcium carbonate
Molecular formula: CaCO3
White powder, non-toxic, light weight, stable in air, slightly hygroscopic.
Uses: Precipitated calcium carbonate is the most widely used inorganic pigment, widely used in rubber, paper, plastics, adhesives, coatings, inks, daily necessities, cosmetics and feed.
Packing: Composite plastic woven bag, 25KG/bag
Superfine light calcium carbonate
Properties: fine particle size of light calcium carbonate, white powder, odorless, average Particle size in the range of 0.1-0.3μm, large specific surface area.
Ultra-fine (active) light calcium carbonate is finer and more uniform than ordinary light calcium carbonate. It is often used as additive of emulsion and pulp. Ultra-fine active light calcium carbonate is widely used in rubber resin, coating, ink, cosmetics and other industries.
