Description

Lewatit MP-62 is a weakly basic, macroporous anion exchange resin designed for the selective removal of acidic components from various process streams. Its core value lies in its high capacity and excellent chemical stability, providing reliable performance in demanding industrial environments. This product is essential for industries requiring high-purity water, efficient catalysis, and the purification of organic and inorganic solutions. The material is identified by the CAS registry number 9062-74-2.

Application

• Water Demineralization & Deionization: Used in mixed-bed or separate-bed systems for the production of high-purity water in power generation, pharmaceuticals, and microelectronics.
• Catalyst Recovery & Purification: Effective for the separation and purification of homogeneous catalysts from reaction mixtures in fine chemical synthesis.
• Sugar & Sweetener Decolorization: Employed in the decolorization and demineralization of sugar syrups, high-fructose corn syrup (HFCS), and other sweeteners.
• Organic Acid Removal: Selectively removes organic acids like citric, acetic, and lactic acids from fermentation broths and chemical process streams.
• Chemical Processing: Purification of chemicals, such as the removal of acidic impurities from alcohols, glycols, and other organic solvents.
• Wastewater Treatment: Applied in the treatment of industrial wastewater to remove anionic contaminants, including nitrates, chromates, and organic acids.

Quality Control

Our Lewatit MP-62 is manufactured under a stringent quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance in terms of total exchange capacity, moisture holding capacity, particle size distribution, and chemical stability. Certificates of Analysis (COA) detailing these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the original container sealed to prevent moisture uptake and contamination. Store away from strong oxidizing agents.
