Good quality weak base anion resin

The weak base functionality makes TA301D could be regenerated easily even using waste caustic left from regeneration of SBA resin. So TA301D could be used multi bed demineralizers to prolong the lifetime of SBA resin and prevent it from organic fouling.

Basic Features:


Water demineralization (deionization), strong acids removal.

Polymer matrix structure:

Macroporous polystyrene crosslinked with divinylbenzene (DVB)


Beige opaque, spherical beads

Functional Group:

Tertiary amine (Dimethylamine)

Ionic form as shipped:

Free base

More information:

Weak base anion resin are like weak acid resins in that the degree of ionization is strongly influenced by pH. Consequently, WBA resin exhibit minimum exchange capacity above a pH of 7.0. The WBA resin does not have a hydroxide ion form as does the SBA resin. These resins merely sorb strong acids, they cannot split salts.
