Which of the following membrane material can withstand 200 °C temperature
EXPLANATION
Membrane Materials & Thermal Stability
- Thermal Resistance of Membrane Polymers:
- PTFE (Polytetrafluoroethylene): A fluoropolymer with outstanding chemical inertness and extreme thermal stability, capable of continuous operation at temperatures up to $200^\circ\text{C}-260^\circ\text{C}$ and across the entire $\text{pH}$ range of $0-14$.
- Polysulfone (PS) and Polyethersulfone (PES): Typical maximum continuous operating temperatures are limited to $75^\circ\text{C}-125^\circ\text{C}$.
- Polyamide (PA): Maximum temperature limits are generally $50^\circ\text{C}-80^\circ\text{C}$.
- Correct Option: Option 1 (PTFE - Polytetrafluoroethylene).
