Understanding Calcium Chloride Specifications, Grades and Supplier Selection

Choosing the right Calcium Chloride (氯化钙) comes down to reading the specification sheet correctly. This guide explains the numbers that matter and how to select a supplier you can trust.

Key Specifications of Calcium Chloride

As an CaCl2 desiccant, the product is defined by a small set of parameters:

• Molecular formula: CaCl2·2H2O / CaCl2
• CAS No.: 10035-04-8 (dihydrate) / 10043-52-4 (anhydrous)
• Appearance: White flake, powder, granules, pellet
• Packaging: 25/1000kg woven bags with PE liner
• Standard: GB/T26520-2011

Grade and Quality Considerations

Not all water plant auxiliary chemicals are equal. For Calcium Chloride, confirm active content, moisture and impurity limits against the cited standard. A reputable CaCl2 desiccant supplier provides a Certificate of Analysis (COA) per batch and supports third-party testing.

Selection Checklist

1. Match the application: Excellent flocculant in environmental protection and water treatment; snow melting, deicing, multipurpose desiccant.
2. Confirm packaging matches your handling (drum vs. bag, 25/1000kg woven bags with PE liner).
3. Verify the standard (GB/T26520-2011) and request documentation.
4. Check lead time and container-load options for export.

Storage and Handling

Store Calcium Chloride in a dry, ventilated area away from incompatible substances. Follow the MSDS for PPE and spill response. Many buyers combine this product with Sodium Hydroxide (Caustic Soda) in a single sourcing plan to reduce freight and admin cost.
