Fiberglass corrugated packing is a specialized structured packing material designed for corrosive liquid-liquid extraction processes. Composed of fiberglass-reinforced plastic, it integrates high chemical resistance with mechanical stability, making it ideal for handling aggressive solvents and acids where conventional materials like metal degrade rapidly. Its unique design ensures consistent performance in harsh environments, critical for maintaining extraction efficiency and process safety.

Material Properties and Structural Design
The packing’s performance stems from its material and structure. Fiberglass, with its inherent resistance to strong acids, alkalis, and organic solvents, prevents chemical degradation, extending service life by years compared to metal alternatives. Its low thermal expansion coefficient minimizes distortion under temperature variations, preserving separation precision. Structurally, the corrugated pattern creates uniform flow channels with a high specific surface area (typically 150-350 m²/m³), maximizing contact between liquid phases and accelerating mass transfer. This design also reduces pressure drop, allowing for higher throughput in industrial extraction towers. Widely used in chemical plants, pharmaceutical production, and environmental treatment, it separates components like organic compounds from inorganic solutions, enhancing product purity and process yield.
