Product Description
High-Density Polyethylene (HDPE) Black, Co-extruded Textured Geomembrane GPF Production line is Equipped with the latest European technology for manufacturing a geomembrane with a co-extruded textured surfaces using ultra high purity nitrogen. GPF HDPE Black, Co-Extruded Textured Geomembrane is a black high-quality product; manufactured in our state of the art Saudi Arabian facility. GPF uses 97.5% pure high density polyethylene virgin polymer, 2.5% carbon black, and trace amounts of antioxidants and UV stabilizer. It is used in different lining applications that require high quality and durable geomembrane with a high frictional resistance. It has embedded smooth edges inside the die head to offer more cost-effective, more consistent, and better welding. Chemical resistance, stress crack resistance, high mechanical properties, dimensional stability and UV stabilization are main features for GPF HDPE Co-extruded Textured geomembrane. All GPF HDPE Products are produced with specification that meets or exceeds GRI-GM13.
