Purolite C150E Cation Exchange Resin.

Purolite C150E Resin is a macroporous strong acid cation exchanger of polystyrene cross-linked with divinylbenzene. The unique structure of this resin allows for high capacity and exceptional physical and chemical stability. The irregular structure of this resin promotes better kinetics and successful diffusion rates in and out of the beads.

Purolite C150E Resin also adsorbs and extracts organic compounds faster and more thoroughly than typical macroporous resins.

On the other hand, it is efficient for water softening in industrial and domestic applications and for large and small demineralization units. Hot water and condensate softening, with temperatures up to 130°C, is a typical application for Purolite C150E.
