plastic tower packing is made of those heat resistant and chemical corrosion resistant plastics, including PE, PP, RPP, PVC, CPVC and PVDF, it has features such as high void ratio, 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 operating temperature in media ranges from 60 centigrade to 150 centigrade 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. (Conjugate Ring, VSP Ring, Pall Ring, Casade Mini Ring, Saddle, Teller Rosetter, Heillex, Polyhedral Hollow Ball, etc. )
