Feature		High void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer.
Advantage		1. Their special structure make it has big flux, low pressure drop, good anti-impaction capability. 2. Strong resistance to chemical corrosion, large void space. energy saving, low operation cost and easy to be load and unload.
Application		These various plastic tower packing are widely used in petroleum and chemical, alkali chloride, gas and environmental protection industries with max. temperature of 280°.

Physical & Chemical Properties
Plastic tower packing can be made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinyiidene fluoride (PVDF) and Polytetrafluoroethylene (PTFE). The temperature in media ranges from 60 Degree C to 280 Degree C.
