We are a trusted supplier and exporter of Sodium Metabisulfite, known for its high purity, consistent quality, and excellent performance in various industrial applications. Our Sodium Metabisulfite (Na2S2O5) is widely used as a reducing agent, preservative, antioxidant, and disinfectant across industries such as water treatment, food processing, textiles, leather, and chemical manufacturing.
Sodium Metabisulfite is a white to slightly yellowish crystalline powder with a characteristic sulfur dioxide odor. It is highly soluble in water and releases sulfur dioxide (SO2), making it effective for sterilization, dechlorination, and purification processes. Its strong reducing and sulfonating properties make it suitable for a wide range of industrial and commercial applications.
