COOLGUARD™ Geomembrane

The Coolguard™ Liner meets the need for an effective material for primary and secondary (long-term) containment of a broad range of chemicals, including both dilute acids and organics.

Coolguard™ is a cost-effective terpolymer alloy coating consisting primarily of Elvaloy® and PVC resins. This unique blend of resins has been optimized to produce a high performance product which is not susceptible to plasticizer migration.

Coolguard™ is dimensionally stable, has excellent UV resistance and does not require earthen cover.
