The materials of plastic pall ring could be PVC , PP, PTFE and PVDF . The temperature tolerance of each material is different. Now Let us study them one by one. 

1.PVC plastic pall ring

The temperature tolerance of PVC material is 110°C. The PVC ring has the characteristics of high porosity high throughput, low pressure drop and low bed height of transmission unit, high flooding point, enough gas-liquid contact area, less in weight, and good efficiency.

2. PP plastic pall ring

The temperature tolerance of material PP pall ring is 80°C.

3. PVDF plastic pall ring

With the resistant temperature of 150°C,the PVDF pall ring has good chemical properties and high temperature resistance,Oxidation resistance and excellent adapt ability to weather.

4.PTFE plastic pall ring

The temperature resistance of PTFE pall ring is 220°C.
