Resin
Features:
Description:
Polymex Resin is a 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:
Polymex Resin is used most widely in sodium form for water softening applications. It can be used also in two-stage de-ionising as the cation exchanger in the hydrogen cycle.
Features:
• High exchange capacity
• High mechanical strength
• Uniform particle with good hydraulics characteristic
• Good Selectivity
• Good Thermo-tolerant characteristic
• Excellent physical and chemical stability
