Coolguard geomembranes are engineered for use in areas where primary and/or secondary containment of hydrocarbons, liquids, aggressive chemicals and other regulated substances is required. Coolguard can handle many petrochemicals in primary contact. Utilized in the field since 1990, Coolguard geomembranes offer a cost-effective, functional alternative to double-walled tanks, concrete-lined embankments and similar protective structures. It is formulated with Dupont Elvaloy® (KEE) as part of a tri-polymer alloy. The Elvaloy polymers were developed to form homogeneous blends with other polymers. Because the are resistant to hydrocarbons and other chemicals, they provide the engineer and end user with a product for many applications where chemical resistance, high physical strength and other unique properties are necessary.
Coolguard withstands a broad range of chemicals with little or no deterioration of physical properties. The superior performance coupled with the flexibility of the Coolguard geomembrane is the result of the combination of select polymer blending, stabilizers and the unique reinforcing mediums. Coolguard is available with six different reinforcements, giving the designer a wide range of physical characteristics to choose from, including a “rip-stop” design. Each one offers unique properties for the application or on-site conditions.
