amberlite ion exchange resin

  • Anion exchange resin for mixed bed
  • A better oxidative stability
  • Better regeneration efficiency
  • A high capacity


Gel type I strong base anion exchange resin is used for water demineralization.

SAG07 Is a gel type I strong base anion exchange resin with polystyrene matrix and quaternary amine (Trimethylamine) function group, crosslinking 7%.

The particle size is in standard gaussian distribution with 0.315-1.25mm >95%.

SAG07 has a better physical & chemical stability compared with SAG04, Its gel structure make it has excellent regeneration efficiency (both in co-current and counter-current systems) and rinse performance.

SAG07 intended for use in the hydroxide form for all types of deionizing systems , such as  in polishing mixed beds. as well as in the chloride form for removal of contaminants such as nitrate, arsenate, chromate, uranium, etc.
