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.
- 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
- Hot Brine Containment
- Secondary Containment Liner Under Heated Tanks
- Bioreactor (High Temperature) Landfills
- Hot Potable Water Containment
- Mining Process Water, Tailing, and Leaching Containments
- Long-term Chlorinated Water Containment
HeatGard® is a high-temperature resistant geomembrane with excellent chlorine and chemical resistance, is fully stabilized against UV light exposure and has excellent stress cracking resistance.
