Description

Calcium Chloride Tetrahydrate is a highly versatile inorganic salt valued for its exceptional moisture-absorbing and de-icing properties. This compound is essential for industrial processes requiring precise humidity control and temperature management. Key industries that rely on this material include construction, food processing, oil & gas, and chemical manufacturing, where it serves as a desiccant, concrete accelerator, brine fluid, and more.

Application

• Concrete Acceleration & Dust Control: Widely used in the construction industry to accelerate the setting time of concrete and control dust on unpaved roads.
• Industrial Desiccant & Dehumidification: Employed as a highly effective drying agent in air and gas drying systems due to its strong hygroscopic nature.
• Food Processing & Preservation: Utilized as a firming agent, electrolyte source, and preservative in various food products and beverages (food grade required).
• Oil & Gas Drilling Fluids: Acts as a component in brine-based drilling fluids to control wellbore stability and density.
• De-icing & Anti-icing Agent: Applied to roadways and surfaces to lower the freezing point of water, preventing ice formation and enhancing safety.
• Chemical Synthesis & Process Chemistry: Serves as a calcium source and drying agent in various organic and inorganic chemical reactions.
• Water Treatment: Used for adjusting water hardness and as a flocculation aid in wastewater treatment processes.
• Tire Ballast & Agricultural Uses: Provides liquid ballast for tractor tires and can be used as a foliar spray to correct calcium deficiencies in crops.

Quality Control

Our Calcium Chloride Tetrahydrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including Industrial, Technical, Food (FCC), and USP/Pharmaceutical grades, each meeting relevant industry specifications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available for every shipment upon request.

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 absorption of atmospheric moisture and caking.
