Green Resin is a heterospherical high capacity strongly acidic cation exchanger in bead form. It is based on cross linked polystyrene and has a gel structure. The resin contains sulphonic acid functional groups. It is supplied moist in the sodium form.
Applications
Green Resin is used most widely in sodium form for potable water softening application. It can be used also in two-stage de-ionising as the cation exchanger in the hydrogen cycle.
