Table of Contents Product Overview Key Features Technical Specifications Applications Company Background Conclusion Product Overview The Macroporous Adsorption Resin AB-8 is a specialized adsorbent material designed for the extraction, separation, and purification of water-soluble and weakly polar substances. Manufactured by Hebei Lijiang Biotechnology Co., Ltd. , this resin is a styrene-type weakly polar copolymer composed of a crosslinking agent (divinylbenzene), monomer (methyl acrylate), and porogen (toluene). Its unique properties make it ideal for applications in pharmaceuticals, food processing, and environmental remediation. The resin's macroporous structure ensures high surface area and efficient adsorption capacity, while its chemical stability allows it to withstand harsh conditions during purification processes. This product is particularly valued for its ability to separate colored organic compounds, as its milky white or light yellow appearance facilitates visual monitoring during operations. Key Features High Selectivity: The resin demonstrates excellent selectivity for organic compounds, even in the presence of inorganic salts, making it suitable for complex mixtures. Chemical Stability: Insoluble in acids, alkalis, and organic solvents, the resin can be used with a wide range of adsorbents and desorbents, such as ethanol, acetone, and methanol. Easy Regeneration: The resin can be regenerated using water, dilute acids, or low-boiling solvents, ensuring long-term cost-effectiveness and sustainability. Excellent Mechanical Strength: Resistant to physical degradation, the resin maintains its structural integrity over extended use, reducing the need for frequent replacements. Visual Convenience: The milky white or light yellow color allows for easy observation of the separation process, enhancing operational efficiency. Technical Specifications Specification Value Appearance Milky white opaque spherical beads Resin Structure PSD (Polystyrene Divinylbenzene) Polarity Weakly polar Moisture Content 65%–75% Particle Size Range 60–16 mesh (0.3–1.25 mm, ≥90%) Average Pore Size 13–14 nm Pore Volume 0.73–0.77 ml/g Porosity 42%–46% Specific Surface Area ≥480 m²/g Adsorption Capacity ≥45 mg/g Applications The Macroporous Adsorption Resin AB-8 is widely used in various industries due to its versatility and efficiency. Key applications include: Pharmaceuticals: Extraction and purification of alkaloids, stevioside, and other bioactive compounds from natural sources.
