DuPont IRC120 Na Ion Exchange Resin Industrial Softening Resin for Water Softeners

Cation Exchange Resin for Hard Water Softening

DuPont™ AmberLite™ IRC120 Na is a high-performance ion exchange resin produced by DuPont.

Basic Information

Type: Gel-type strong acid cation exchange resin.

Matrix Structure: Composed of styrene/divinylbenzene copolymer, which provides the resin with strong chemical resistance.

Functional Group: Sulfonic acid group, which gives the resin strong acid cation exchange properties, enabling it to exchange with various cations in water.

Physical Form: Amber-colored, translucent spherical particles with uniform size, good fluidity, and packing properties, facilitating loading and use in ion exchange columns.

Appearance: Amber, translucent

Type: Cation exchange resin

Ionic Form: Insoluble in water

Acid-Base Property: Acidic

Packaging Specification: 25kg

Temperature Range: 5-150°C

Performance Characteristics

Efficient Ion Exchange Capacity: High exchange capacity, capable of rapidly and selectively adsorbing and removing cations such as calcium, magnesium, and heavy metals from water, significantly reducing water hardness and improving water purity. Excellent performance in hard water softening, desalination, and metal ion removal.

Excellent Physical and Chemical Stability: Maintains stable performance over a wide temperature range (typically 5-150°C), resistant to corrosion from various chemicals and solvents, ensuring long-term reliability and extended service life.

Good Mechanical Strength: High mechanical strength of resin particles, resistant to breakage and wear, capable of withstanding water flow impact and pressure changes during water treatment, ensuring stability and continuity of the resin bed, and reducing clogging and loss issues caused by resin breakage.

Easy Maintenance and Regeneration: Regular regeneration restores the ion exchange capacity of the resin, extending its service life. High regeneration efficiency minimizes resource consumption and wastewater discharge during regeneration, reducing operating costs and offering significant environmental and sustainability benefits.
