Our Calcium Chloride 77% Flakes is a high-purity upgraded version of dihydrate calcium chloride. Relying on the high-quality brine resources in the core salt chemical production area of Shouguang, it is processed by a dedicated “multi-stage refining + low-temperature tablet making” process. It has a CAS number of 10043-52-4 and a chemical formula of CaCl₂·2H₂O. The product is a uniform and white thin sheet with a thickness precisely controlled between 0.3 and 0.8mm. Compared with products with a 74% content, its purity has increased by 3 percentage points and the impurity content has been significantly reduced. The calcium chloride content is stable at 77%±0.8%, the sodium chloride impurity is ≤2.5%, the water-insoluble matter is ≤0.1%, and the sulfate impurity is ≤0.05%. The hardness is moderate and the clarity of the aqueous solution after dissolution is high. While retaining the advantages of its flaky form, the product’s hygroscopicity is increased by 15%, with a freezing point as low as -18℃. The heat release during dissolution is more stable, effectively avoiding quality fluctuations in downstream products caused by impurities.

What are the advantages of high purity?

Compared with ordinary flake calcium chloride, the 77% high-purity version, with its quality upgrade, brings three differentiated core values and has become the first choice for mid-to-high-end industrial customers:

Firstly, it has lower impurities and better protects the equipment. The precise control of impurities such as sodium chloride and sulfate can significantly reduce scaling and corrosion within production equipment, extend the equipment maintenance cycle, and is particularly suitable for precision chemical equipment and continuous production lines, thereby lowering the maintenance costs for customers in the later stage. Secondly, it has more stable performance and is suitable for fine craftsmanship. The improvement in purity makes the product’s hygroscopicity and dissolution rate more stable. The performance difference between batches is ≤0.5%, eliminating the need for customers to frequently adjust production parameters and ensuring the product qualification rate in the fine processing stage. Thirdly, more comprehensive compliance ensures worry-free exports. The 77% Flakes of Calcium Chloride fully comply with the EU REACH regulation and the high standards of HG/T2327-2004 in China. For export, SGS full-item test reports can be directly provided, covering 18 key indicators.

What are the application scenarios?

Based on its high purity, 77% calcium chloride tablets are primarily suitable for mid-to-high-end industrial and fine chemical applications, achieving “precise matching + performance upgrade”:

In the fine chemical field, as an auxiliary raw material for dye and pigment production, its low impurity characteristics prevent any impact on product color and purity. In high-end dry packaging scenarios, it can be used for moisture-proof storage of electronic components and precision instruments. Its thin, sheet-like design allows for flexible packaging into breathable small packages. Within 24 hours, its moisture absorption rate can reach 140% of its own weight, maintaining humidity below 50% in enclosed spaces, ensuring the safe storage of high-value products. In the food processing industry, this product meets relevant standards for food contact materials and can be used as a coagulant in the production of soy products and canned foods, enhancing product texture stability without leaving any odor residue. In high-end building materials production, this product is used for the rapid setting of special concrete, accelerating setting and improving the uniformity of concrete strength, suitable for high-standard construction projects such as bridges and tunnels.

Quality Traceability

To meet our customers’ core demand for quality control, we have established a full-process quality traceability system: each batch of 77% calcium chloride tablets has a unique batch number. From raw material testing and random sampling during production to comprehensive finished product inspection, the testing data for 16 key indicators are traceable. Customers can enter the batch number on our website to view the complete test report. The production process uses a fully automated control system to precisely control the temperature and thickness of the sheets, ensuring consistent quality for every product.

Customization Support

We also offer exclusive customization services: sheet thickness can be adjusted according to customer needs (0.3-1mm), and we provide high-end packaging solutions, such as 25kg vacuum-sealed bags and 50kg moisture-proof aluminum foil bags, to prevent moisture and contamination during transportation and storage. For fine chemical customers, we can provide customized testing items and add testing indicators such as heavy metals and harmful impurities. We have a professional technical team to provide one-on-one technical support, including raw material matching and feed ratio optimization, helping customers improve production efficiency.

we always put our customers’ needs first. With its high purity, stable performance, and excellent service, 77% calcium chloride tablets have become a long-term partner of more than 30 mid-to-high-end industrial customers worldwide.
