Plastic Pall Ring packing is particularly suitable for use in medium and low-temperature (60-150 degrees) stripping, absorption and scrubbing towers in the petroleum, chemical, chlor-alkali, gas, environmental protection and other industries, as well as in carbon dioxide degassing towers, ozone contact reaction towers and other reaction towers as contact packing.

The following are some important parameters of the plastic pall rings: 

Density: The density of plastic pall rings usually ranges from 0.85 to 1.05 g/cm³. This density makes the plastic pall rings very lightweight and easy to carry. 

2. Hardness: The plastic ball rings have extremely high hardness and can maintain their shape in various environments. This makes plastic ball rings widely used in various application fields, such as packaging, toys, household items, etc. 

3. Flexibility: The plastic ball rings possess excellent flexibility, allowing for easy bending and stretching. This flexibility enables the plastic ball rings to accommodate various shapes and size requirements. 

4. Chemical Resistance: The plastic pall rings exhibit excellent chemical resistance to a wide range of substances and can be used for a long time in various environments. 

5. Oil Resistance: The plastic pall rings exhibit excellent oil resistance and can be used for a long time in an oil-containing environment. 

6. Heat Resistance: The plastic pall ring also has excellent heat resistance and can be used for a long time at temperatures exceeding 120°C. 

7. Low-temperature resistance: The plastic pall ring also has excellent low-temperature resistance and can be used for a long time at a temperature of -50°C. 

In summary, the plastic pall rings possess many unique characteristics, enabling them to be widely used in various application fields. They have the advantages of being lightweight, having high hardness, good flexibility, chemical resistance, oil resistance, heat resistance, and low-temperature resistance.
