Amberlite IRA402 Cl

Summary

Product identification

AMBERLITE™ IRA402 Cl is an industrial-grade, Type 1 strongly basic, clear gel, anion exchange resin. It features a crosslinked polystyrene matrix with a trimethyl ammonium functional group.

Properties

• Physical form: Pale yellow translucent spherical beads
• Matrix: Styrene divinylbenzene copolymer
• Functional group: Trimethyl ammonium
• Ionic form as shipped: Chloride
• Total exchange capacity: ≥ 1.20 eq/L (Cl⁻ form)
• Moisture holding capacity: 49 to 60 % (Cl⁻ form)
• Shipping weight: 670 g/L
• Particle size:
  • Uniformity coefficient: ≤ 1.6
  • Harmonic mean size: 0.600 to 0.750 mm
  • < 0.300 mm: 1.0 % max
• Reversible swelling: Cl⁻ → OH⁻ ≤ 30 %

Suggested operating conditions

• Maximum operating temperature: 60°C
• Minimum bed depth: 700 mm
• Service flow rate: 8 to 40 BV*/h
• Regeneration:
  • Regenerant: NaOH
  • Level: 60 to 150 g/L
  • Concentration: 2 to 4 %
  • Minimum contact time: 30 minutes
  • Slow rinse: 2 BV at regeneration flow rate
  • Fast rinse: 4 to 8 BV at service flow rate

*1 BV (Bed Volume) = 1 m³ solution per m³ resin.

Hydraulic characteristics

• Figures in the original document show bed expansion and pressure drop data as a function of flow rate and water temperature. These data are valid at the start of the service run with clear water and a correctly classified bed.

Limits of use

AMBERLITE IRA402 Cl resin is suitable for industrial uses. For specific applications such as pharmaceutical, food processing, or potable water, consult with Rohm and Haas for advice on resin choice and operating conditions.
