XR-5  is classified as an Ethylene Interpolymer Alloy (EIA). It is very stable, with low thermal expansion and contraction properties and come in factory panels up to 15,000 square feet (1400 square meters) for less field seaming. Example projects include floating covers, tank farms, wastewater impoundments, landfill liners and potable water applications. XR-5 is capable of performing in harsh environments.

Manufacturing processes and fabrication systems meet the industry's most stringent performance demands. XR-5 Liner is highly resistant and non-degradable with extreme puncture and tear resistance, as well as dimensional stability under high loads and temperature fluctuations.


XR-5 can be seamed by hot air or wedge welded  under controlled conditions into panels at one of CLI's three fabrication facilities. It is available in 30 or 40 mil thicknesses.  CLI fabricates XR-5 in panels of up to 15,000 sf.
