GSE Environmental Awarded Patent for High Temperature Geomembrane

HOUSTON, TX – (November 9, 2017) – GSE Environmental is pleased to announce the issuance of US Patent No. 9,518,176 B2 for its High Temperature Geomembrane Liners and Master Batch Compositions. GSE High Temperature Liner is our newest innovative geomembrane, specially engineered to withstand prolonged exposure to temperatures up to 100°C (212°F).

When the temperature exceeds 60°C, property loss, oxidation, and UV degradation are accelerated in standard polyethylene geomembranes, which can reduce strength properties. GSE’s team of engineers collaborated with resin producers to develop innovative HDPE resin formulations for use in high temperature applications. When used in conjunction with GSE’s proprietary high temperature stabilization formula, the result is a liner that delivers the same durability and chemical resistance as any GSE geomembrane and will retain these properties when exposed to sustained temperatures up to 100°C.

“The High Temperature Liner continues GSE’s history of developing and improving products in response to industry needs and through collaboration with our customers. It is through innovative new product development such as this, that GSE continues to be known as a pioneer in geosynthetics,” said Ed Zimmel, Vice President, Engineering.

GSE’s High Temperature Geomembrane has been used in numerous applications and industries around the world. For more information about High Temperature Liner and GSE’s full line of products and services, visit
