Coolguard geomembrane is formulated with Dupont Elvaloy® (KEE) as part of a tri-polymer alloy. The Elvaloy® polymers are tough plastics developed for homogeneous blends with other polymers, because they are resistant to hydro-carbons and other chemicals.

Coolguard 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, stabilisers and the unique reinforcing mediums.
