PPS is often selected when polyester is not enough for temperature, moisture, or acidic flue gas conditions.
It should be evaluated with oxygen content and temperature peaks in mind.

PPS Filter Media
Good resistance to acid gas and hydrolysis compared with polyester
Advantages
- Good high temperature performance
- Useful for acidic flue gas
- Can be combined with PTFE membrane
Limitations
- Sensitive to high oxygen at elevated temperature
- Higher cost than polyester
- Requires accurate flue gas data
