|---|---|
| Appearance | White powder or pellets |
| CaCl₂ content | ≥94% |
| Alkalinity (as Ca(OH)₂) | ≤0.25% |
| NaCl | ≤5% |
| MgCl₂ | ≤0.5% |
| Sulfate (as CaSO₄) | ≤0.05% |
| Water-insoluble matter | ≤0.15% |
| pH | 6–11 |
Confirm particle size and test conditions, including the pH test method, for your order.

Confirm the physical form, applicable requirements and supporting documents for your intended use and destination.
Match content, form and impurity limits.
1. For drying and moisture control, specify powder or pellets, particle size, equipment and contact materials.
2. For oilfield or refrigeration brines, provide the target solution concentration and impurity requirements alongside the 94% minimum CaCl₂ content.
3. For food processing, request the food-grade specification and documents for your intended use and destination; content alone does not determine suitability.
Applications
Drying & dehumidification
A hygroscopic material used in industrial drying and moisture-control applications. Share the process, contact materials and required particle size to discuss the suitable grade.
Drilling & completion fluids
Calcium chloride for oilfield brines, drilling and completion-fluid applications. Share the target solution concentration, fluid programme and impurity limits for product selection.
Refrigeration brines
Calcium chloride is used to prepare brines for refrigeration and ice-making systems. Specify the required solution concentration and operating conditions when discussing the solid product.
Packaging, samples & storage
Standard net weights are 25 kg and 1,000 kg. PP bags, PE bags, pails, drums and private labels can be agreed for the order. Specify the pack material, net weight, artwork and pallet preference.
The usual minimum bulk order is one container. Loading quantity and dispatch are confirmed by order. Sample quantity and buyer-paid international courier charges are agreed before dispatch.
Store in a cool, dry, well-ventilated place, protected from moisture and direct sunlight. Keep packs tightly sealed when not in use.
Documents for your selected grade
Request a TDS and SDS for the selected grade and a representative COA for evaluation. For a quotation, include the physical form, application, quantity, packing and destination.
