When it comes to flexible membrane solutions, XR liners are among of the toughest and most reliable on the market. Useful when high resistance to chemicals, tears, heat, and expansion is required. EIA, a high-tech polymer, is used in XR liners (Ethylene Interpolymer Alloy). XR liners may be found in a number of different thicknesses, colors, and compositions to accommodate needs such as potable water grade, oil resistance, and Arctic cold temperature resistance. For more than 40 years, XR liners have been used for a wide variety of water containment applications, such as pond liners, secondary containment, floating covers, wastewater, baffles, and drinking water.
