HeatGard® Geomembranes

Critical Containment In The Harshest Conditions

Your critical containment infrastructure demands the best in longevity, toughness, and chemical resistance. HeatGard® is made from next-generation bimodal resins that retain antioxidants for an unprecedented length of time. This retention over time is vital to extending the service life of a geomembrane.

Environmental Stress Cracking (ESCR), a common failure mechanism, can be combatted with lower-density resins, which generally lead to less stress cracking risk. Unfortunately, this also leads to lower chemical resistance. With HeatGard® made from bi-modal resins, the resulting product has a stronger crystal from both the high molecular weight portion and the lower molecular weight polyethylene. The result is a more robust product with a very low risk of stress cracking and a high level of chemical resistance.

What Makes HeatGard So Resilient?

Withstands High-Temperature Exposure

Typical HDPE materials are unsuitable for extended periods above 60°C [140°F]. HeatGard® can withstand continuous use at 85°C [185°F] for over 20 years.

Excellent Longevity In Harsh Environments

  • Chlorine resistant (70% HPOIT retained after one year)
  • UV stable (80% HPOIT retained 1600 hours UV)
  • Brine resistant (70% HPOIT retained after one year at 100°C

Wide Format Rolls for Fast Installation

Fewer seam welding requirements makes for a quicker installation and lower instances of possible failure.

Additional Features

  • Long-life at high temperatures
  • Superior chlorine resistance
  • Excellent chemical resistance
  • Hot liquid resistance (brine)
  • Potable hot water resistance
  • Over a year of exposure testing completed
HeatGard® Geomembranes
