Description

Calcium Chloride Dihydrate is a highly versatile inorganic salt known for its exceptional hygroscopic and exothermic dissolution properties. This compound is critical for industrial processes requiring precise moisture control, temperature management, and ionic strength. It serves as an essential raw material and processing aid across diverse sectors, including deicing, food processing, construction, and oil & gas, where reliability and consistent quality are paramount for operational success.

Application

• Deicing & Dust Control Agent: Widely used for melting ice on roads, sidewalks, and airport runways, and for suppressing dust on unpaved surfaces.
• Food Additive & Processing Aid: Employed as a firming agent (E509), electrolyte in sports drinks, and a calcium source in food fortification and cheese making.
• Concrete Accelerator & Desiccant: Accelerates the setting time of concrete in cold weather and acts as a powerful desiccant in industrial drying processes.
• Oil & Gas Drilling Fluids: Used to increase the density and control the swelling of clays in brine-based drilling and completion fluids.
• Industrial Refrigerant & Heat Transfer Fluid: Functions as a brine for refrigeration plants and in ice-making equipment due to its low freezing point.
• Water Treatment & Waste Processing: Applied for pH adjustment, as a coagulant aid, and for sludge conditioning.
• Tire Ballast & Soil Stabilization: Used as a liquid ballast in agricultural tires and to stabilize soil for construction projects.
• Laboratory & Pharmaceutical Uses: Serves as a source of calcium ions in buffer solutions, cell culture media, and certain pharmaceutical formulations.

Quality Control

Our Calcium Chloride Dihydrate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Products are available in various grades, including Technical, Food Grade (FCC), and USP/Pharmaceutical grades, each meeting their respective specifications. Comprehensive testing is performed, and a Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed immediately after use to prevent caking and absorption of atmospheric moisture. Store away from incompatible materials such as strong oxidizers.
