Calcium Chloride Dihydrate (CAS: 10035-04-8) is a white crystalline solid renowned for its hygroscopic properties and its ability to significantly lower the freezing point of water. These characteristics make it an invaluable chemical across a spectrum of industries. For procurement professionals, R&D scientists, and formulation chemists, understanding its applications and how to efficiently source it is key to operational success. This guide provides insights into its uses and procurement strategies, focusing on finding reliable suppliers and competitive prices.

Key Applications Driving Demand for Calcium Chloride Dihydrate:

  • De-icing and Snow Melting: Its primary use, especially in colder climates, where it effectively melts ice and snow on roads, sidewalks, and airport runways. It works at lower temperatures than common salt, making it a superior choice for challenging conditions.
  • Dust Control: The hygroscopic nature of Calcium Chloride Dihydrate attracts moisture from the air, keeping surfaces damp and suppressing dust formation on unpaved roads, construction sites, and mining areas. This leads to improved air quality and reduced maintenance needs.
  • Food Industry: As a food additive (E509), it plays a crucial role as a firming agent for canned vegetables like tomatoes and pickles, preventing them from becoming mushy. It's also used to adjust the salt balance in evaporated milk to prevent coagulation during sterilization and to enhance the texture of various other food products.
  • Concrete Acceleration: In construction, it acts as an accelerator for cement setting, particularly beneficial in cold weather, allowing for faster project completion and improved structural integrity.
  • Industrial Drying: Its strong affinity for water makes it an excellent desiccant for drying gases and organic liquids in industrial processes, ensuring product purity and preventing moisture-related degradation.
  • Refrigeration Brines: Concentrated solutions of Calcium Chloride Dihydrate are used in refrigeration systems as a low-freezing point brine.

Procurement Strategies for Calcium Chloride Dihydrate:

Securing a consistent and cost-effective supply of Calcium Chloride Dihydrate requires a strategic approach. When looking to buy this chemical, consider the following:

  • Identify Reputable Manufacturers: Partnering with established manufacturers, especially those in regions known for chemical production like China, can ensure quality and competitive pricing. Look for suppliers with robust quality control systems and relevant certifications.
  • Compare Prices from Multiple Suppliers: Do not settle for the first offer. Requesting multiple quotes allows you to benchmark the price and identify the most economically viable option for your specific volume requirements.
  • Understand Grade Requirements: The intended application dictates the required purity. Food-grade or pharmaceutical-grade Calcium Chloride Dihydrate will be priced higher than industrial-grade. Ensure you are procuring the correct grade to avoid unnecessary costs or quality issues.
  • Negotiate Volume Discounts: For significant quantities, bulk purchasing directly from a manufacturer can lead to substantial discounts. Discuss long-term supply agreements to potentially lock in favorable prices.
  • Consider Logistics and Lead Times: Factor in shipping costs and delivery times. A reliable supplier will have efficient logistics in place to ensure timely delivery, preventing operational disruptions.
