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.
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.
Based on its high purity advantage, Calcium Chloride 77% Flakes are mainly suitable for mid-to-high-end industrial and fine chemical scenarios, achieving "precise matching + performance upgrade":
In the field of fine chemicals, as an auxiliary raw material for the production of dyes and pigments, the low impurity characteristic can avoid affecting the color and purity of the products. We have stably supplied products to many fine chemical enterprises in Jiangsu and Zhejiang, helping them improve product quality and successfully enter the international market. In high-end drying scenarios, it is used for moisture-proofing in the storage of electronic components and precision instruments. The thin sheet form can be flexibly packed into small breathable packaging. The moisture absorption rate within 24 hours can reach 140% of its own weight, and it can keep the humidity in a closed space below 50%, ensuring the safety of high-value product storage. In the field of food auxiliary material processing, it complies with relevant standards for food contact materials and can be used as a raw material for coagulants in the production of soy products and canned food, enhancing the stability of product texture without leaving any odor residue. In the production of high-end building materials, it is used for the rapid setting of special concrete, which can accelerate the setting while enhancing the uniformity of concrete strength, and is suitable for high-standard construction projects such as Bridges and tunnels.
In response to customers' core demand for quality controllability, we have established a full-process quality traceability system: Each batch of Calcium Chloride 77% Flakes has a unique batch code. From the raw brine testing, random inspection during the production process to the full inspection of the finished product, the test data of 16 key indicators can all be traced. Customers can enter the batch number on the official website to query the complete test report. The production process adopts a fully automated control system to precisely control the temperature and thickness of the sheet, ensuring uniform quality of each piece of product.
We also offer exclusive customization services: the thickness of the sheet can be adjusted according to customer needs (0.3-1mm is available), and high-end packaging solutions such as 25kg vacuum sealed bags and 50kg moisture-proof aluminum foil bags are provided to prevent moisture absorption and contamination during transportation and storage. For fine chemical customers, customized testing items can be provided, with additional testing indicators such as heavy metals and harmful impurities. Equipped with a professional technical team, we provide one-on-one technical support for customers, including raw material matching and optimization of feeding ratios, to help them enhance production efficiency.
As a source Factory that has been deeply engaged in the chemical industry for 20 years, we always take customer needs as the core. Calcium Chloride 77% Flakes, with its high purity, stable performance and excellent service, has become a long-term partner of over 30 medium and high-end industrial customers worldwide.
