High Temperature Geomembranes

Prolonged exposure to temperatures above 60oC (140oF) can have a negative effect on standard polyethylene geomembranes. When the temperatue exceeds 60oC, the liner's mechanical properties more rapidly break down, causing acceleration in stress cracking and oxidation. This can lead to potential failure.

GSE’s innovative team of engineers combined high temperature resins with GSE’s proprietary formula of carbon black, UV stabilizers, and antioxidants to develop a liner that withstands the effects of extreme temperatures. GSE High Temperature Liner delivers the same durability and chemical resistance as any GSE geomembrane, but will retain its mechanical and physical properties in applications with sustained elevated temperatures of up to 100°C (212°F).

GSE High Temperature Liner is essential for high temperature applications where liner integrity and long service life are required.
