Calcium Chloride 74% Min Flakes (CaCl₂) is a highly versatile, fast-acting inorganic salt valued across numerous industries for its exceptional hygroscopic properties, rapid dissolution, and wide functional benefits. Manufactured in controlled environments to ensure ≥74% purity, this material appears as white, free-flowing flakes that dissolve easily in water and generate heat upon hydration. Its unique chemical behavior makes it one of the most widely used industrial-grade salts in construction, refrigeration, dust control, oil & gas, and water-treatment applications.

Chemical Characteristics & Composition

Calcium Chloride (CaCl₂) is a calcium-based halide compound known for its strong affinity for moisture. The flake form, with a minimum 74% active content, offers a balanced combination of purity, stability, and ease of handling. It absorbs moisture rapidly from surrounding air, making it excellent for dehumidification and moisture control operations. When mixed with water, it produces an exothermic reaction (releasing heat), which is especially useful in accelerating chemical processes, curing, and de-icing.

Physical Properties

Key Features & Benefits

1. Strong Hygroscopic Performance

One of the most distinctive features of Calcium Chloride is its ability to absorb moisture quickly and efficiently. This property makes it a preferred choice for use in moisture-control systems, drying processes, humidity regulation in storage rooms, and as a desiccant.

2. Rapid Dissolution & Heat Release

When dissolved, Calcium Chloride flakes release a large amount of heat. This exothermic reaction accelerates many industrial processes, such as:

Concrete setting and curing

De-icing and frost prevention

Brine preparation for refrigeration systems

3. Effective in Low Temperatures

Unlike many other salts, Calcium Chloride remains effective even at sub-zero temperatures. This makes it highly suitable for roads, pavements, industrial floors, cold storage areas, and other surfaces requiring ice-melting performance in very low temperatures.

4. Dust Control Efficiency

Calcium Chloride is widely used for controlling dust on:

Construction sites

Unpaved roads

Mining areas

Industrial yards

By absorbing moisture from the air and binding fine particles together, it reduces airborne dust significantly.

Road stabilization

Soil solidification

Foundation work in cold regions

2. Industrial & Commercial Dehumidification

Because of its strong moisture-absorbing nature, CaCl₂ flakes are used in:

Moisture absorbers

Cargo & container desiccants

Storage & warehouse humidity control

Air-drying units

3. Refrigeration & Cold-Chain Systems

Calcium Chloride brine solutions are used as refrigerants due to their excellent thermal stability and heat-transfer properties. They operate reliably at low temperatures and resist freezing, making them suitable for industrial cooling units.

4. Oil & Gas / Drilling Fluids

In drilling operations, CaCl₂ helps to:

Increase mud density

Stabilize shale formations

Reduce water activity in fluids

Prevent swelling of clays

Its effectiveness in high-salinity environments makes it a standard component in many drilling and completion fluids.

5. Dust Suppression & Soil Stabilization

Applied on unpaved roads and industrial yards, Calcium Chloride absorbs moisture from the environment, keeping the soil compact and dust-free. Its long-lasting effect helps reduce maintenance costs and improves working conditions.
