Description

Calcium Chloride Hydrate is an inorganic salt compound widely utilized for its moisture-absorbing and de-icing properties. Its significance lies in its versatility as a highly effective desiccant, a source of calcium ions, and a freezing point depressant. This product is essential for industries ranging from construction and oil & gas to food processing and pharmaceuticals, where control over moisture, dust, or ionic balance is critical.

Application

• Dust Control & Road Stabilization: Applied to unpaved roads and construction sites to suppress dust and stabilize the base layer.
• De-icing & Anti-icing Agent: Used on roads, walkways, and in refrigeration brines due to its exothermic dissolution and ability to lower the freezing point of water.
• Industrial Drying & Desiccant: Employed in air and gas drying processes, and as a desiccant in packaging, due to its strong hygroscopic nature.
• Concrete Acceleration: Added to concrete mixes to accelerate the setting time and provide early strength gain, especially in cold weather.
• Oil & Gas Drilling Fluids: Serves as a source of calcium ions in brine-based drilling fluids to stabilize shale formations and control clay swelling.
• Food Processing: Used as a firming agent, preservative, and electrolyte in sports drinks, and for cheese making (food grade specifications required).
• Pharmaceutical & Laboratory: Acts as a calcium source in medicinal formulations and as a drying agent in various chemical processes.

Quality Control

Our Calcium Chloride Hydrate is manufactured under a stringent quality management system. Products undergo rigorous testing to ensure they meet the required specifications for their intended application, whether industrial, technical, food grade (FCC), or pharmaceutical (USP/EP) standards. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 absorption of atmospheric moisture and caking.
