Plastic VSP (Vertical Spiral Packing) Ring is a high-performance random packing made from thermoplastics such as PP, PE, PVDF, or CPVC.
Its vertical spiral rib design enhances liquid distribution, reduces pressure drop, and increases mass transfer efficiency.
With excellent chemical resistance, mechanical strength, and thermal stability, Plastic VSP Rings are widely used in gas absorption, stripping, and scrubbing processes across chemical, environmental, and metallurgical industries.

Features

  • High Efficiency Design — Vertical spiral ribs improve liquid film formation and gas–liquid contact.
  • Low Pressure Drop — Open structure ensures smooth gas flow and minimizes resistance.
  • Excellent Chemical Resistance — Suitable for strong acids, alkalis, and corrosive gases.
  • Durable & Lightweight — Strong mechanical strength with light weight for easy handling.
  • Anti-Fouling Structure — Large open area reduces risk of clogging and scaling.
