Plastic Corrugated Structured Packing Product Description

Plastic Corrugated Structured Packing is a versatile and cost-effective regular packing designed for mass transfer operations in corrosive and moderate-temperature environments. Manufactured from polypropylene (PP), PVC, PVDF, or CPVC sheets, it features the same corrugated geometry as metal structured packings—with alternating inclined channels that promote uniform liquid spreading and high gas-liquid contact efficiency. Its lightweight nature, exceptional chemical inertness, and low price point make it an ideal choice for absorption, scrubbing, and cooling tower applications across the chemical, environmental, and metallurgical industries.

Product Highlights

• Outstanding Corrosion Resistance: PP, PVC, PVDF and CPVC are inherently resistant to most inorganic acids, alkalis, and salt solutions, ensuring long service life in aggressive chemical environments where metal packings would corrode.
• Lightweight & Easy Installation: Weighing only 1/8 to 1/5 of metal packings, the plastic blocks are easy to handle and install, reducing tower structure load and installation costs.
• High Mass Transfer Efficiency: The corrugated structure with embossed or textured surface ensures uniform liquid film formation and high effective interfacial area, delivering theoretical plates of 1.0–4.0 per meter depending on type.
• Low Pressure Drop: Regular open-channel geometry minimizes gas flow resistance, significantly lowering energy consumption in fan-driven scrubbers and cooling towers.
• Cost-Effective Solution: Lower material cost compared to metals and ceramics, combined with excellent durability, makes it an economical choice for large-volume towers.
• Customizable Designs: Available in various specific surface areas (125–450 m²/m³) and easily fabricated into blocks of any diameter, with options for perforated or plain sheets to optimize wetting and throughput.
