Calcium Hypophosphite

Calcium hypophosphite

Calcium hypophosphite has the chemical formula Ca(H2PO2)2,It has very low solubility and is a positive salt. In China, it is classified as a non-hazardous chemical and is primarily used in animal feed additives, non-halogenated flame retardants, and food additives. The CAS is 7789-79-9. It is a phosphate sodium salt with reducing and antioxidant properties. At room temperature, its solubility in water is 16.7g/100g water, and its aqueous solution has a PH less than 7, exhibiting weak acidity.

The main raw materials for the production of calcium hypophosphite are sodium hypophosphite and calcium chloride. In nylon PA6, calcium hypophosphite can be compounded with other phosphorus and nitrogen flame retardants to achieve good flame retardancy.The price of calcium hypophosphite is closely related to that of yellow phosphorus and sodium hypophosphite. The dispersion, purity, and control of impurities during production significantly impact quality.

Calcium hypophosphite | Application and prices of calcium hypophosphite

Calcium hypophosphite has certain applications in chemical plating, nutritional supplementation, and flame retardancy, among other industries. It is one of the few phosphates with antioxidant properties. The price of calcium hypophosphite is closely linked to the market prices of yellow phosphorus and sodium hypophosphite. The amount added as a flame retardant depends on the formulation, generally below 30%.
