XR-5 Material
Information
XR-5®
Woven Composite Fabric
XR-5®
XR-5®
is a scrim supported flexible liner, an extremely tough woven
composite fabric of Dupont Dacron® polyester fibers that has been molecularly
coated with sophisticated compounds that are minimally degradable in adverse
weather conditions and environments. With this combination, the liner and
coating offer a unique balance of performance features.
XR-5®
material offers maximum performance such as a highly resistant, non-degradable
membrane surface with extreme puncture and tear resistance, dimensional
stability under high loads and extreme temperature fluctuations. XR-5® is also
easily heat weldable, as the coating compounds bond molecularly when heat
welded.
XR-5 one side coated per pass assures the bonding process and a very high
quality finished material. The exclusive coating compound contains Dupont
Elvaloy®, which is essentially non-crystalline and therefore not susceptible to
environmental stress cracking.
XR-5's flexibility makes it possible to easily fit the liner around irregularly
shaped applications. XR-5®also is proven to prevent seepage of caustic
chemicals.
XR-5's
resistance to chemicals is evident since the geomembrane has a long history with
hydrocarbon containment and has been lab tested for over ten years in constant
contact with crude oil. Additionally, field seams and CQA are minimal
since the flexible XR-5 ®can be factory manufactured into panels approximately
15,000 square feet each.
Nobody wants to trust his lined application to untried liners or liners with
known problems. With a 20-year-plus track record in tough applications
throughout the world, XR-5® geomembrane is the first choice when max tensile
strength, high UV resistance and minimal thermal expansion and contraction are
required.
