      Acrylic vs. Styrenic Type 1 Anion Resins

      The pros and cons of using acrylic versus styrene type 1 resins.

        ADVANTAGES DISADVANTAGES

      ResinTech SBACR
      (Acrylic Resin)

      Very good regeneration efficiency

      Very temperature sensitive leadingto a generally shorter life
       

      Highly resistant to organic fouling, better than styrene type strong baseanion resins

      0

      ResinTech SBG1P
      ResinTech SBG1
      (Styrenic Resins)

      Can be regenerated with very warm caustic (up to 140°F) leading to the lowest possible silica leakage

      Highly susceptible to organic fouling
       

      Generally longer life expectancy than acrylic resins

      Somewhat poorer regenerationefficiency
       

      Lower cost than acrylic resin

      Acrylic resins are ideally suited for all waters (below 75°F net average temp) with high organic fouling potential where the lowest possible silica levels are not required. Acrylic resins are not U.S. FDA approved.

      Styrenic resins are better suited for general demineralizing applications for low silica, high purity, and high temperature requirements and for waters that do not have a high organic fouling potential.
