Coolguard™ HR (KEE – Elvaloy® Terpolymer) is a geomembrane liner, that can handle many petrochemicals and chemicals. Coolguard is very flexible and can be installed in the complex areas. It is thermally welded (or RF) so that large panels and pipes, or similar penetrations and complex details can be created on site, or pre-fabricated. Coolguard is UV-resistant and does not need to be buried; it is dimensionally stable. It has a high strength specially woven rip-stop scrim that provides enhanced overall physical performance. Because of the scrim, Coolguard has a high puncture resistance. Typical applications for Coolguard are lining in lagoons, ponds, tanks or other impoundments, floating covers and similar containments.
