Are Pall rings resistant to high temperatures

The high temperature resistance of Pall rings varies depending on the material:

1. ** Polytetrafluoroethylene (PTFE) Pall ring ** :

Excellent high temperature resistance, working temperature can reach **160℃**, and can still maintain 5% elongation at low temperature to -196℃.

2. ** Ceramic Pall Ring ** :

Excellent high temperature resistance, can withstand the high temperature of about 1200℃**, suitable for high temperature reaction or distillation process.

3. ** Electronic PFA Pall Ring ** :

The long-term use temperature range is wide, usually *-80 ° C to 200 ° C ** (some data mention up to -196 ° C to 260 ° C), and it still maintains good mechanical properties at high temperatures.

4. **PVC Pall Ring ** :

The temperature range is relatively low, usually between **60-150 ° C **, suitable for medium and low temperature environments.

In summary, when selecting Pall ring, the material should be matched according to the temperature and medium characteristics of the specific working conditions.
