ResinTech BSM-50 is a borate form antimony and silica selective hybrid gel type 1 strong base anion resin. Hydrated iron oxide is monoatomically dispersed throughout the polymer, giving the product hybrid properties. The borate form hybrid is able to remove chloride and sulfate in addition to silica, antimony125, and other radionuclides. BSM-50 is stable and is intended for all nuclear applications such as spent fuel pools that contain borated water.
