RE: High-temp resilient liner
Can you please guide me to suppliers of high-temp, approx. 215 F (100 C) liners?
Also, the liner should be able to handle up to 200,000ppm TDS (total dissolved solids) of salts.
I am looking for HDPE or similar liner.

Reply: Wow, what a question! My answer might not be to your liking but here it is: The highest that geomembrane manufacturers recommend for usage is between 150–170 F. Even then, you will not get a 20-year warranty since at these high temperatures the degradation mechanisms (oxidation mainly) are most active. Of course, different resins behave differently and you might inquire [with manufacturers] about EPDM (ethlylene propylene diene monomer), which is a thermoset polymer.
