Product Description:

Calcium chloride is an inorganic salt compound with the chemical formula CaCl₂ (anhydrous) / CaCl₂·2H₂O (dihydrate). It appears as white powder, flakes, granules or crystals, featuring strong hygroscopy, high solubility in water with exothermic dissolution, stable chemical properties and weak corrosivity. Classified by water content into anhydrous calcium chloride and calcium chloride dihydrate, and by application standards into industrial grade (Grade AA/Grade A) and food grade (complying with national standard GB 1886.224), different specifications are suitable for multi-field industrial production and food processing needs.

Industrial grade calcium chloride has high main content and controllable impurities with excellent hygroscopic and solidification performance, serving as a basic raw material in industrial production. Food grade calcium chloride strictly follows the national food additive standards with heavy metals and harmful impurities far below the limit values, featuring high safety and being directly applicable to food processing links. All products are non-hazardous with convenient storage and transportation, supporting customized packaging and specifications to meet the bulk procurement and personalized needs of different customers. Widely used in industry, food, construction, environmental protection and other industries, it is a practical and versatile chemical raw material.
