ResinTech WBMP is a styrenic macroporous weak base anion resin with moderate strong base functionality. WBMP is a weak base anion resin with very good rinse characteristics that can be efficiently regenerated with a variety of alkaline chemicals, or with waste caustic left over from regeneration of strong base anion resin.  WBMP is intended for use in multibed demineralizers. It can also be used in resource recovery systems and for selective ion removal (when used in the acid salt form). WBMP is supplied in the free base form, or can be special ordered in the acid salt form (when ordered as WBMP-HCl), or with the strong base sites regenerated into the hydroxide form (when ordered as WBMP-OH).
