Commodity: Calcium chloride Molecular formula CaCl2 H.S code 28272000 Product feature Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous. Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature, Specifications: Analysis Item Standard Calcium chloride (CaCl2) 74%min,77% min,94%min Total Chlorinated Alkali: (NaCl) 5.0%max Magnesium Chloride(MgCl2) 0.5%max Insoluble matter in water 0.25%max Calcium Sulfate (CaSO4): 0.2%max Ferric Oxide (Fe2O3) 0.025%max Heavy Metal as Cu., Pb., Cd., Cr., Hg., As 0.005%max Application Mainly used in drying, melting snow for airport express and street, concrete desiccant and concreting fast, removing dust and oil industry.
