Plastic Structured Packing -Corrugated Plate Packing / Wire Guaze Packing
Plastic Structured Packing has similar structure with metal structured packing, which can be divided into plate packings and wire gauze packings. Plastic structured packing can
be made of PP, PA, PVDF, CPVC and other plastic materials, which has excellent high temperature resistance performance and corrosion resistance performance. It is an alternative
to ceramic structured packing.
Types
• Wire gauze packings: Wire gauze packings is commonly made of PP materials
• Plate packings: Plate packings can be perforated plate packings or no perforation packings. Perforated plate packings can supply better mass transfer efficiency and
smooth surface plate packings supply good stiffness.

Plastic Structured Packing Features
» High efficiency, high capacity and low pressure drop as metal structured packing.
» Excellent corrosion resistance performance to be used in high corrosive applications.
» Better high temperature resistance than metal structured packing and ceramic structured packing. Working
» Temperature of PP packings can reach 100 °C and PVDF packings can reach 150 °C.
» Perforated plates packings with small holes on surface increase mass transfer efficiency.
» High sheet stiffness of no perforation packings in less separation requirements applications.
