Product Description
GPF LLDPE standard black, smooth geomembrane is a high quality, black colored product; that is manufactured in our state-of-the-art Saudi Arabian facility. GPF uses 95% pure linear low density polyethylene virgin polymer and 2.5% carbon black with trace amounts of antioxidants and UV stabilizer. No other additives, filters or extenders are used. This product is flexible and has high elongation properties allowing it to be used in various applications that expect some subgrade movement. Chemical resistance, stress crack resistance, high mechanical properties, dimensional stability and UV stabilization are main features for GPF LLDPE Smooth Geomembrane. All GPF LLDPE Products are produced with specification that meets or exceeds GRI-GM17.
