Description

Calcium Chloride Hexahydrate is a highly versatile inorganic salt valued for its exceptional moisture-absorbing and heat-releasing properties. This compound is essential for industrial processes requiring precise humidity control, temperature management, and calcium ion supply. It serves as a critical raw material for diverse sectors including deicing, dust control, concrete acceleration, food processing, and as a laboratory reagent.

Application

• Deicing & Dust Control Agent: Widely used for melting ice on roads, parking lots, and sidewalks, and for suppressing dust on unpaved surfaces.
• Concrete Accelerator: Added to concrete mixes to accelerate the setting time and generate heat during curing in cold weather.
• Desiccant & Drying Agent: Employed in industrial drying processes and as a laboratory desiccant due to its strong hygroscopic nature.
• Food Additive: Used as a firming agent, preservative, and electrolyte in sports drinks, canned vegetables, and cheese making (food grade specifications required).
• Brine Refrigeration: Acts as a secondary refrigerant in industrial refrigeration systems and ice rinks.
• Oil & Gas Drilling: Utilized to increase the density of drilling fluids and completion brines.
• Water Treatment: Applied for pH adjustment and as a source of calcium ions in water softening and treatment processes.
• Chemical Synthesis: Serves as a calcium source and reagent in various chemical manufacturing processes.

Quality Control

Our Calcium Chloride Hexahydrate is manufactured under strict quality management systems. Products undergo rigorous analytical testing to ensure they meet specifications for purity, heavy metal content, and other critical parameters. We can supply material compliant with various grades including Technical, Food Grade (FCC), and USP/EP for pharmaceutical applications. A Certificate of Analysis (COA) is provided with each batch to guarantee traceability and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent caking and absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from incompatible materials.
