Basic Chromium Sulphate is a cornerstone chemical in the leather and textile industries, particularly renowned for its pivotal role in the chrome tanning process. This inorganic compound, typically supplied as a dark green powder, possesses unique chemical properties that facilitate the transformation of raw hides into durable, flexible, and stable leather. Beyond leather production, it is also indispensable in the manufacture of certain dyestuffs, contributing to color fastness and stability.

NINGBO INNO PHARMCHEM CO.,LTD. stands as a reliable source for high-quality Basic Chromium Sulphate powder. Our product is meticulously manufactured to meet stringent industry standards, ensuring consistent performance and purity essential for sensitive applications like leather tanning and dye synthesis. The inherent quality of the material directly impacts the quality of the final product, whether it's supple leather goods or vibrantly colored textiles.

The physical and chemical characteristics of Basic Chromium Sulphate make it ideally suited for its primary uses. It typically presents as a dark green, free-flowing powder. A key measure of its quality is the percentage of chromium oxide (Cr2O3), usually ranging from 24% to 26%, and its basicity, which falls within the 31% to 35% range. These parameters are crucial for controlling the tanning process. The powder is known for its good solubility in water, which allows for easy preparation of tanning liquors and ensures uniform distribution of chromium complexes within the hide matrix. A low percentage of water insolubles is vital to prevent undesirable precipitates that could impair leather quality.

A significant advantage of the Basic Chromium Sulphate supplied by NINGBO INNO PHARMCHEM CO.,LTD. is its production method. Utilizing an organic reduction process minimizes or eliminates the presence of hexavalent chromium (Cr6+), a form of chromium recognized for its environmental and health concerns. This manufacturing approach aligns with increasing global demand for more sustainable and environmentally conscious chemical products. The resulting product not only performs effectively but also supports greener manufacturing practices in downstream industries.

In leather tanning, Basic Chromium Sulphate works by reacting with the collagen fibers in the hide. The chromium ions cross-link the collagen chains, enhancing the hide's thermal stability, resistance to decomposition, and mechanical strength. Our product offers excellent penetration into the hide, ensuring that the tanning agent reaches all layers for a uniform tan. High absorption of Cr2O3 is also a critical performance indicator, maximizing the efficiency of the tanning bath and reducing waste. The basicity plays a crucial role in controlling the reaction rate and the uptake of chromium by the hide, allowing tanners to achieve desired leather properties.

Beyond leather, Basic Chromium Sulphate is employed in the production of certain chromic compounds and serves as a mordant or component in dyestuffs. It is particularly noted for its use in dyeing khaki fabrics, where chromium helps fix the dye to the fiber, providing excellent color fastness against washing and light exposure. Its versatility makes it a valuable chemical across multiple sectors.

The packaging of Basic Chromium Sulphate is designed to maintain its quality and integrity during storage and transport. Standard options include 25kg bags, often constructed from durable materials like PP or Kraft paper, sometimes with moisture-proof inner liners. Proper storage is essential; the material should be kept in a dry, cool area away from direct sunlight and moisture to prevent caking and degradation. While not classified as highly toxic, standard industrial safety precautions should always be followed during handling, including adequate ventilation and personal protective equipment.
