Description

Phenol, 4-Methyl-, Polymer With Diethenylbenzene And 1-Ethenyl-4-Ethylbenzene is a synthetic polymeric resin, specifically a cross-linked copolymer derived from p-cresol, divinylbenzene, and 4-ethylstyrene. This engineered material is valued for its robust chemical structure, providing excellent thermal stability and tailored porosity for selective adsorption and separation processes. It is primarily utilized in industrial applications requiring high-performance polymeric adsorbents, ion-exchange media, and specialty polymer matrices for advanced material science and purification technologies.

Application

• Industrial Adsorption Media: Used in fixed-bed columns for the selective removal of organic compounds, heavy metals, or specific ions from process streams and wastewater.
• Ion-Exchange Resin Precursor: Serves as a base matrix for the synthesis of specialized ion-exchange resins used in water treatment, hydrometallurgy, and catalysis.
• Polymer Support/Matrix: Acts as a solid support for catalyst immobilization, reagent grafting, or in solid-phase synthesis for pharmaceutical and fine chemical production.
• Chromatography Stationary Phase: Employed in the preparation of packing materials for preparative and analytical chromatography due to its controlled pore structure and surface chemistry.
• Specialty Composite Materials: Incorporated as a functional filler or reinforcing agent to enhance the thermal and mechanical properties of advanced polymer composites.
• Molecular Sieve Applications: Utilized for size-selective separation processes based on its engineered polymeric network and pore size distribution.

Quality Control

Our production of this polymeric resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as particle size distribution, porosity, cross-linking density, and functional group capacity are rigorously tested. Certificates of Analysis (COA) detailing specific lot characteristics are available upon request, supporting compliance with relevant industrial and material specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture uptake, which may affect performance.
