DURA-SKRIM® KQ Series geomembranes consist of reinforced flexible polypropylene. Exceptional physical properties are achieved by incorporating high levels of ethylene propylene rubber into polypropylene with dense scrim reinforcement for excellent dimensional stability and puncture resistance. In addition, the heavy duty cross-directional reinforcement provides unmatched tear and tensile strengths. Dura-Skrim KQ Series polypropylene membranes do not contain plasticizers that can leach out and hinder long-term flexibility and performance. Dura-Skrim KQ Series provides outstanding resistance to environmental stress cracking even in elevated temperatures and chemical environments. Dura-Skrim KQ Series is certified under the NSF/ANSI Standard 61, Drinking Water System Components - Health Effects.
