Calcium Chloride

Calcium Chloride 74% Flakes (Dihydrate) – Product Overview
Calcium Chloride Dihydrate 74% Flakes, chemical formula CaCl₂·2H₂O, is a white to off-white, flake-form hygroscopic material with high solubility in water. It is an economical industrial-grade product, typically containing about 74% CaCl₂ content (equivalent to dihydrate form), and is widely used for its excellent moisture absorption, de-icing, and calcium ion supply properties.
Common applications include:
   •    Road de-icing and snow melting
   •    Dust control on unpaved roads
   •    Oil and gas drilling fluids (as weighting agent and shale inhibitor)
   •    Concrete acceleration and antifreeze additive
   •    Water treatment and brine preparation
   •    Desiccant in various industries
Produced mainly in China via evaporation and flaking processes, it complies with industrial standards such as GB/T 26520-2021 (Calcium chloride for industrial use) for general applications.
