Description

Rexyn 101 (H) is a high-performance, strongly acidic cation exchange resin widely used in industrial purification and separation processes. Its core value lies in its exceptional capacity and stability for removing cationic impurities from aqueous and non-aqueous streams. This product is essential for industries requiring high-purity water, metal recovery, and catalytic applications. Key sectors that rely on this resin include pharmaceuticals, power generation, hydrometallurgy, and chemical synthesis.

Application

• Demineralization & Water Purification: Primary use in mixed-bed and polishing units to produce high-purity water for power plants, laboratories, and microelectronics.
• Pharmaceutical Processing: Purification of intermediates, active pharmaceutical ingredients (APIs), and solvents; used in antibiotic purification and as a catalyst.
• Hydrometallurgy & Metal Recovery: Selective extraction and concentration of valuable metals like copper, nickel, and rare earth elements from process leach solutions.
• Chemical Catalysis: Acts as a solid acid catalyst in esterification, alkylation, and condensation reactions, offering easy separation and reusability.
• Sugar & Sweetener Industry: Decolorization and deashing of sugar syrups, and purification of high-fructose corn syrup (HFCS).
• Wastewater Treatment: Removal of heavy metal cations (e.g., lead, cadmium) and ammonium ions from industrial effluent.
• Food & Beverage Processing: Softening of process water and stabilization of products like fruit juices and wines.
• Nuclear Industry: Treatment of low-level radioactive wastewater for cation removal.

Quality Control

Our Rexyn 101 (H) is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets consistent performance specifications for exchange capacity, moisture content, particle size distribution, and chemical stability. While produced to industrial grade standards, specifications can be adjusted to meet specific application needs. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep the original container sealed to prevent moisture uptake and contamination. Do not allow the resin to freeze or be exposed to extreme heat.
