Product Description
GPF HDPE Smooth, Conductive Geomembrane is a high quality, conductive product; that is manufactured in our state-of-the-art Saudi Arabian facility. It is manufactured using integrated, specially formulated high electrically conductive carbon black compound in the bottom layer with pure polyethylene virgin polymer, and trace amounts of antioxidants and UV stabilizer to form a good conductive bottom surface of geomembrane to perform in field leak location detection using spark test according to ASTM D7240. No other additives, filters or extenders are used. This Product is used in applications that required post installation testing on the geomembrane liner system to ensure the high quality and durable of the project. Excellent Chemical resistance, Stress crack resistance, High mechanical properties, Dimensional stability and UV stabilization are main features for GPF HDPE Smooth, Conductive Geomembrane. A colored surface on one side and bottom black conductive surface are produced as per the customer’s needs. All GPF HDPE Products are produced with specification that meets or exceeds GRI-GM13.
