Features Of DuPont AMBERLITE MB 20 Ion Exchange Mixed Bed Resin

  1. Premixed, pre-equilibrated cation and anion exchange resins in optimal 1:1 volume ratio for consistent high-purity water production.

  2. Engineered for low sodium leakage and ultra-low silica breakthrough, enabling resistivity >18.0 MΩ·cm in polishing applications.

  3. High physical and osmotic stability ensures extended service life and resistance to bed fouling under cyclic operation.

  4. Uniform spherical bead morphology supports low pressure drop and excellent hydraulic performance in cartridge or column systems.

  5. Regenerable with standard acid and caustic solutions—compatible with conventional mixed-bed regeneration protocols.

Typical Applications Of DuPont AMBERLITE MB 20 Ion Exchange Mixed Bed Resin

  1. Final polishing stage in ultrapure water (UPW) systems for semiconductor manufacturing.

  2. Pharmaceutical-grade water purification meeting USP <711>, EP, and JP pharmacopeial requirements.

  3. Power plant boiler feedwater polishing to prevent turbine scaling and corrosion.

  4. Laboratory analytical water systems requiring Type I reagent water per ASTM D1193.

  5. Electronics cleaning rinse water where ionic contamination must be minimized to sub-pptr levels.
