Tank-Flex 30 Mil LLDPE Black/Gray Membrane

Tank-Flex is a co-extruded linear low density polyethylene geomembrane developed for applications requiring enhanced flexibility along with a combination of high strength and impact resistance. These elements are critical for earthen pits, ponds and reliable above ground tank lining systems.

Tank-Flex includes fine partial carbon black for protection from UV radiation and thermal degradation on one side. A gray color on the other side minimizes thermal expansion while providing a cooler surface. Contrasting colors provide for ease of detection of accidental damage. Both sides are designed for ease of welding in the factory or field.
