PowerMax NXS50 B is a borate form hybrid anion resin selective for silica and antimony. NXS50 B contains hydrated iron oxide crystals monatomically dispersed throughout the polymer. It absorbs antimony, silica, and other contaminants by a combination of ion exchange and adsorption. PowerMaNXS50 B is intended for removing trace levels of antimony and can also be used to remove silica from borated process waters.

PowerMaNXS50 B is supplied in the borate form.
