LLDPE Black Co-extruded Textured Geomembrane

Product Description

GPF LLDPE Black, Co-extruded 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. 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. It is flexible and has a high elongation property which makes it used in different applications that might have subgrade movement. Chemical resistance, stress crack resistance, high mechanical properties, dimensional stability and UV stabilization are main features for GPF LLDPE Co-extruded Textured Geomembrane. All GPF LLDPE Products are produced with specification that meets or exceeds GRI-GM17.

Notes:

  1. One (1) measurement taken every 1 meter along roll width – 10% lowest individual of 10 values.
  2. Carbon Black Dispersion (only near spherical agglomerates) for 10 different views: 9 in Categories 1 or 2 and 1 in Category 3.
  3. Standard test conditions: 190 oC / 2.16 kg.
  4. Roll Width and Length have a tolerance of ± 1%.
