Temperature Resistant HDPE Geomembrane Liner -70°C to 110°C Extreme Cold Climate Dam Canal Freeze Thaw Protection

Extreme Temperature HDPE Geomembrane -70°C to +110°C

Engineered for operation in the most extreme climates, this HDPE geomembrane liner maintains flexibility and mechanical integrity across a temperature range of -70°C to +110°C. The specialized polymer formulation ensures reliable performance in arctic freeze-thaw conditions and desert high-temperature environments.

Temperature Performance

• Service temperature range: -70°C to +110°C
• Low temperature brittleness: passes at -70°C (ASTM D746)
• Cold crack resistance: no cracking at -60°C
• Heat aging resistance: >90% strength retention at 110°C
• Dimensional stability: <±2% across temperature range

Suitable Applications

Arctic and subarctic containment systems, high-altitude dam lining, freeze-thaw exposed canal liners, desert solar evaporation ponds, geothermal containment, and permafrost region waste management facilities.
