PP CPVC Plastic Teller Rosette Ring tower Tellerette Packing Ring
Plastic Rosette Ring is made from heat resistant and chemical corrosion resistant plastics. 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 60°Cto 150°C. 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..
