Product Description

Product Description

 Calcium Chloride

Calcium chloride is a white or slightly yellowish solid inorganic compound, belonging to the salt class. It is a typical ionic halide and is widely used in multiple fields due to its high solubility, hygroscopicity and dehydrating property.

Depending on its hydration form, it exists in different physical forms. The most common one is the dihydrate. Its high solubility enables it to dissolve rapidly in water, releasing a large amount of heat, and thus it is very useful in applications that require rapid heating or drying.

Applications

1.Industrial & Engineering:De-icing/Anti-icing, Concrete Accelerator, Concrete Accelerator,Desiccant

2. Papermaking:Pitch Control
Water Hardness Adjustment
De-inking Aid
Effluent Treatment

3.  Pharmaceuticals: injection for acute hypocalcemia or magnesium toxicity; oral supplements.

4. Environmental & Safety:Precipitates fluorides, sulfates, and heavy metals from wastewater.

Product features

Key Performance: Exceptional hygroscopicityExothermic dissolution: 74 g dissolves in 100 g water at 20 °C, releasing ≈83 kJ/mol—ideal for self-heating packs
• Freezing-point depression: 30 % solution freezes at ≤ –50 °C; de-icing speed 2–3× faster than NaCl
Chemical Stability: Neutral salt at room temperature; melts at 782 °C. Reacts with NH3to form CaCl2·8NH3
Neutral salt at room temperature; melts at 782 °C. 
Hardness adjustment: In food processing, calcium chloride is used to adjust hardness and coagulant.
Nutritional supplement: In agriculture, calcium chloride is used as a soil conditioner and plant nutritional supplement.

Packing & Delivery

Calcium chloride products can be provided in different specifications according to customer needs. 

Common ones include:

Purity: 94%, 96%, 98%, 99%, etc.
Shape: spherical, spiny spherical, etc.
Packaging: 25kg/bag, 50kg/bag, 1000kg/barrel, etc.

Storage

Calcium chloride must be stored in a cool, dry, well-ventilated warehouse, shielded from direct sunlight and any water ingress. Use double-sealed packaging—an inner plastic liner plus an outer woven bag or drum—to block atmospheric moisture and prevent caking. If ambient humidity is high, lay moisture-barrier pallets on the floor and run dehumidifiers, while keeping oxidizers, acids, and food-grade chemicals in segregated zones to avoid cross-contamination.

Transport 

Schedule shipments of calcium chloride only during clear weather, avoiding rain and peak heat periods. Vehicles must be equipped with waterproof tarps and spill-containment kits, and co-loading with oxidizers or foodstuffs is strictly prohibited. Handle packages gently during loading and unloading to prevent ruptures; for tanker trucks, fit grounding chains to dissipate static electricity and display clear chemical labels throughout the journey, ensuring continuous ventilation for safe transit.

FAQ

Q: What's the lead time for orders?

A: At once!

Q: Can you customize packaging?
A: Absolutely! We can customize any size and type of packaging according to customer needs.

Q:Do you provide samples?
A: Yes, you can contact our sales staff if you need samples.

Q: What documents do you provide for export?
A: Full export package (Commercial Invoice, Packing List, Bill of Lading, COC, etc.).

Q: How do I place an order?
A: Contact us via email/phone/WhatsApp for a quote, then confirm with a PO.

Q:In what fields is calcium chloride mainly used?
In the industrial field, calcium chloride is a commonly used road snow melting agent, which can quickly melt ice and snow; used in oil drilling, it can stabilize the mud layer and control the performance of drilling fluids; as a desiccant, it can absorb moisture in the air and be used to dry gas and liquid; in construction, it can be used as an antifreeze to lower the freezing point of concrete and prevent freezing at low temperatures. 

Q: Can calcium chloride products still be used if they are agglomerated?
A:Because calcium chloride is highly hygroscopic, caking is common. If used for industrial purposes such as snow melting and drying, agglomeration will not affect its chemical properties and main functions, and it can still be used normally. However, if food-grade calcium chloride agglomerates, it is necessary to evaluate whether the agglomeration affects its purity and hygiene indicators. It is recommended to contact the supplier for confirmation to avoid affecting food safety.

Q:How to deal with questions about the quality of calcium chloride products?
A:If you have any questions about product quality, please properly retain the product's batch information, packaging and related certificates, and contact our customer service staff in a timely manner. We will arrange professional and technical personnel to follow up, provide product testing report interpretation, re-testing and other services, and negotiate with you to develop a reasonable solution based on the contract and quality standards.
