Aluminum Sulfate

CAS: 10043-01-3

EC: 233-135-0

Aluminum Sulfate is a versatile inorganic salt used primarily in water treatment as a coagulant, aiding in the removal of impurities. Also valued in papermaking and dye fixation, this stable compound dissolves easily, enhancing process efficiency and reliable results.

Sodium Bisulfite

CAS: 7631-90-5

EC: 231-548-0

Sodium Bisulfite is a reducing agent widely used in water treatment for dechlorination and in the pulp and textile industries for bleaching control. Its sulfite-based chemistry helps neutralize excess chlorine, protecting equipment, maintaining product quality, and ensuring regulatory compliance.

Sodium Metabisulfite SMBS

CAS: 7681-57-4

EC: 231-673-0

Sodium Metabisulfite is a powerful reducing agent often used in water treatment (dechlorination), food preservation (antioxidant), and bleaching. Its sulfurous properties help safeguard product quality, prevent oxidation, and maintain color stability across diverse industries.

Sodium Sulfate

CAS: 7757-82-6

EC: 231-820-9

Sodium Sulfate is a widely used salt in detergents, pulp and paper, and textile dyeing. Known for its high solubility and stable nature, it serves as a filler or processing aid. Its compatibility with various chemical reactions makes it a reliable choice in many industrial applications.
