China Basic Chrome Sulphate (BCS) is an essential tannery chemical used in the production of leather products. It is derived from the reaction between sodium dichromate and sodium sulphide in an aqueous solution. BCS is a greenish-yellow crystalline powder that is insoluble in water but readily soluble in dilute acids. As a tannery chemical, BCS is used as a primary agent for the fixation of chrome into the collagen fibers found in animal hides. This process enhances the durability and stability of leather products, making them more resistant to water, heat, and wear. Besides, BCS also improves the leather's physical properties, such as tensile strength, elongation, and tear resistance. Currently, China is the world's largest producer and exporter of BCS, with a considerable market demand from tanneries worldwide. The BCS price in China is relatively competitive, making it a preferred choice for many tanneries that seek quality leather products with an affordable cost factor. In conclusion, China Basic Chrome Sulphate is a vital tannery chemical that plays a significant role in the production of high-quality leather products. Its unique properties and competitive price make it a popular choice among tanners and leather manufacturers worldwide.
