Cation Resin G Ion Resin is produced in Bangladesh but is marketed as a brand with “Origin: USA” on several distributor websites.

  • Brand: G‑Ion (OEM brand from Bangladesh, labeled “Origin: USA”)

  • Type: Strong acid cation-exchange resin (styrene–divinylbenzene matrix with sulfonic (–SO₃H) functional groups) Forms Available: Typically supplied in Na⁺ form (softening resin) and convertible to H⁺ form (for full demineralization)

That suggests it may be formulated or originally developed in the U.S., with production in Bangladesh.

Operating Conditions & Regeneration

  • pH Range: Suitable over 1–14

  • Max Temp: 120 °C (Na⁺ form); 100 °C (H⁺ form)

  • Regeneration:

    • Na⁺ form: 8–12 % NaCl brine; contact time ≥ 30 min — rinse: 10–15 gal/cu.ft (~40–60 L)

    • H⁺ form: Typically with acids (e.g., HCl or H₂SO₄) for use in mixed-bed or demin filters

Applications

  • Water Softening & Pure Water Production: Removes hardness ions (Ca²⁺, Mg²⁺) by exchanging for Na⁺

  • Chemical, Pharmaceutical & Food Industries: Softening pre-process, demineralization, and catalysis roles

  • Heavy Metal Removal: Often used for iron, manganese, etc.

Applications

    • Strong Acid Cation (SAC): Active across the full pH spectrum and used for general softening/demineralization

    • Weak Acid Cation (WAC): Specifically carboxylic type, functional in neutral-to-alkaline conditions, slower exchange rate

    • Mixed-Bed Resin: Cation + anion combined to achieve ultra-pure water; typically 2:3 cation:anion ratio

Summary

    • G‑Ion GC-100 strong acid cation resin g ion (Na⁺ form) is:

      • Standard-sized, high-capacity beads (≥ 4.5 mmol/g),

      • Suitable for 1–14 pH and up to 120 °C,

      • Regenerable with common brine,

      • Ideal for household and industrial water softening and pre-treatment,

      • Convertible to H⁺ form for deeper purification when used in tandem with anion resins.
