Product Description
High-Density Polyethylene (HDPE) Standard Black, Smooth Geomembrane GPF HDPE 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 97.5% pure high density polyethylene virgin polymer resins and 2.5% carbon black with trace amounts of antioxidants and UV stabilizer. It is used in different lining applications that require high quality and durable geomembrane. Chemical resistance, stress crack resistance, high mechanical properties, dimensional stability and UV stabilization are main features for GPF HDPE Smooth geomembrane. All GPF HDPE Products are produced with specification that meets or exceeds GRI-GM13.
