White crystalline, hrdroscopic and deliquescent, sodium hypophosphite is easily soluble in water and alcohol.


Mainly used as reductant for chemical plating. The advantage of sodium hypophosphite is to obtaine a dense and uniform nickel phosphorus film for both large equipment and tiny components, articles with complicated external shape of convex concave lines or internal wall of deep-hollows, the surface of non-metals such as plasitc, ceramics, glass etc.

The film possess a good surface hardness and abrasion resistance, sodium hypophosphite is widely used in electronics, aviation mechanism, and petroleum fields. It is also used as interface activator, M.W moderator, thermo-stablizer for synthetic resins and additive for foods.
