Sodium hypophosphite Use
Sodium Hypophosphite (SHPP) acts as a reducing agent to supply the electrons necessary for the Electroless Nickel process. The EN process allows for uniform plating thickness on not only metal objects, but also plastics and ceramics.
SHP may be used as a reducing agent or antioxidant in chemical processing, also may be used as a partial fire retardant.
