Plastic random packing Brief Introduction Plastic tower packing is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60to 150. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc. Physical & chemical properties of plastic random packing Performance / Material PE PP RPP PVC CPVC PVDF Density (g/cm3) 0.94-0.96 0.89-0.91 0.93-0.94 1.32-1.44 1.50-1.54 1.75-1.78 Operation Temp.
