Industrial Grade Magnesium Sulfate is a high-purity, white crystalline compound composed of magnesium, sulfur, and oxygen, typically available in hydrated forms such as heptahydrate (MgSO₄·7H₂O), monohydrate (MgSO₄·H₂O), or anhydrous (MgSO₄). This versatile chemical is manufactured under strict quality control to meet industrial demands for consistency, solubility, and purity. It is widely used across industries including textiles, leather, construction, chemical synthesis, water treatment, and fireproofing.
In the textile and dyeing industry, magnesium sulfate acts as a stabilizing agent, helping to control the pH level and improve dye absorption. In the leather industry, it is utilized during tanning processes to enhance chemical penetration and final texture. It is also used in the manufacture of magnesium-based chemicals, paper pulp, ceramics, ABS plastics, fire-retardant formulations, and as an additive in electroplating baths to improve conductivity and metal adhesion.
In industrial wastewater treatment, magnesium sulfate serves as a flocculant and buffer, aiding in heavy metal precipitation and pH adjustment. It can also be employed in concrete and cement applications to regulate setting time, increase strength, and reduce cracking due to shrinkage. Furthermore, magnesium sulfate is added in the aluminum smelting industry as a surface treatment component to enhance color anodization.
This product is valued for its high solubility in water, stable chemical properties, and cost-effective performance in a wide array of industrial processes. It is typically supplied in 25kg or 50kg woven bags or bulk jumbo bags, with customized packaging options available on request.
