Hypo Phosphorous acid Application/Usage
Hypo Phosphorous acid may be used as Reducing Agent for its strong but slow reducing action, and be used in the production
of Hypophosphite Salts (i.e., Calcium, Magnesium, Manganese, Potassium, Iron, and Ammonium) which are in turn used in
synthetic fibers as wetting dispersing, emulsifying, and anti-static agents.
Hypo Phosphorous acid also can be used as Bleaching Agent, Color Stabilizer, Chemical Intermediate, Neturalizing Agent,
Wetting Agent, Antioxidant or as a stimulant in pharmaceuticals.
Package of Hypo Phosphorous acid
25kg, 250kg plastic drum, or 1000L IBC tote, total 19.2-20mt/20'FCL palletized.
