Calcium Carbonate

2.Molecular formula :     CaCO₃

3.Molecular weight:100.09

4. CAS：471-34-1 

5.Property: white powder, colorless, tasteless. Stable in the air. Is almost insoluble in water, insoluble in alcohol. Case of dilute acetic acid, dilute hydrochloric acid, dilute nitric acid boiling bubbles occur, and dissolved. Heated to898 ℃ begins to decompose to calcium oxide and carbon dioxide.

6.Usage : The role of calcium carbonate light: widely used in papermaking, plastics, plastic film, chemical fiber, rubber, adhesives, sealants, household chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, putty, carpet layers packaging, pharmaceutical, food (such as chewing gum, chocolate), feed, and its role are: increasing product volume, reduce costs, improve processing performance (such as regulating the viscosity, rheological properties, curing properties), increased dimensional stability, reinforcement or semi-reinforcing and improve printing performance, increase their physical properties (such as heat resistance, extinction, abrasion resistance, flame resistance, whiteness, gloss), ect.
7. Package and storage : Product is in 2 layer bags, inner is PE bag, outside is woven bag, Net weight: 25kg/bag.

8.Executive standard ; ISO9001-2000
