Description

Calcium Chloride is a versatile and highly effective inorganic salt with the CAS registry number 10043-52-4. It is valued across numerous industries for its powerful hygroscopic properties, ability to lower the freezing point of water, and its role as a source of calcium ions. This makes it an essential raw material for sectors ranging from construction and de-icing to food processing and pharmaceuticals.

Application

• De-icing and Dust Control Agent: Widely used for melting ice and snow 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 provide early strength development, especially in cold weather.
• Desiccant and Drying Agent: Employed in industrial drying processes for gases and organic liquids due to its strong hygroscopic nature.
• Food Additive (E509): Used as a firming agent, preservative, and electrolyte in products like canned vegetables, sports drinks, and cheese making.
• Oil & Gas Drilling Fluids: Serves to increase the density and stability of brine-based drilling fluids.
• Water Treatment: Acts as a flocculant aid and for adjusting the hardness of water in treatment plants and swimming pools.
• Pharmaceutical & Nutraceutical Ingredient: Used as a calcium source in dietary supplements and in certain medical applications.
• Industrial Process Chemical: Utilized in refrigeration brines, as a coagulant in latex production, and in waste treatment.

Quality Control

We supply Calcium Chloride in various grades, including Industrial, Technical, Food Grade (FCC), and USP/Pharmaceutical grades. Our products undergo rigorous quality testing to ensure compliance with relevant industry standards such as FCC, USP, ACS, and REACH. A comprehensive Certificate of Analysis (COA) is available for every batch upon request, detailing purity, assay, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic nature, store in a cool, dry, and well-ventilated area. Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture (caking). Store away from incompatible materials.
