Description

Cation Exchange Resin 50W-X12, 200 - 400 Mesh is a strongly acidic, sulfonated polystyrene-divinylbenzene copolymer supplied in the sodium form. This high-capacity, gel-type resin is essential for efficient ion exchange processes, offering superior performance in demineralization and purification applications. It is a critical component for industries requiring reliable water treatment, chemical processing, and purification of process streams.

Application

• Industrial Water Demineralization: Primary use in mixed-bed and two-bed deionization systems to produce high-purity water for power generation, manufacturing, and laboratory use.
• Chemical Processing & Catalysis: Acts as a solid acid catalyst in organic synthesis reactions and for the purification of chemical intermediates.
• Sugar & Sweetener Industry: Employed in decolorization and demineralization processes for sugar syrups, high-fructose corn syrup, and other sweeteners.
• Pharmaceutical Purification: Used for the purification of antibiotics, amino acids, and other active pharmaceutical ingredients (APIs).
• Hydrometallurgy & Metal Recovery: Facilitates the recovery and separation of valuable metals like copper, nickel, and uranium from process solutions.
• Condensate Polishing: Critical in power plants for removing ionic impurities from steam condensate to protect boilers and turbines.

Quality Control

Our Cation Exchange Resin 50W-X12 is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including total exchange capacity, moisture holding capacity, particle size distribution, and uniformity coefficient to ensure consistent performance and reliability. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from strong oxidizing agents. The resin is supplied moist; do not allow it to dry out, as this may cause irreversible damage to the polymer matrix.
