ASTM Smooth HDPE Geomembrane Sheet Corrosion Resistance For Mining Industry

ASTM Chemical Corrosion Resistance Smooth HDPE Geomembrane For Mining Industry


HDPE smooth geomembrane is made from high grade polyethylene raw material,

adding carbon black ,antioxidant, anti-aging and UV resistance component.

It adopted the first class automatic production equipment and three-layer pressing technology.

All products are in accordance with GB/GRI/ASTM GRI 13 GRI17 standard.


0.5mm or 0.75mm-thickness is used for pond liner

1.5mm-thickness is used for landfill

2.0mm-thickness is used for dam liner

Benefits of HDPE

  • The most chemically resistant member of the polyethylene family due to its dense configuration.

  • Field welded with hot wedge welders and extrusion welders. These factory quality welds are virtually stronger than the sheet itself.

  • The best QC-QA testing capabilities in the marketplace.

  • No need to cover the liner because it is UV stable = cost-effective.

  • Available in roll stock and come in varying thicknesses ranging from 20 to 120 mil depending on your requirements.


Applications of HDPE

  • Irrigation ponds, canals, ditches & water reservoirs
  • Mining heap leach & slag tailing ponds
  • Golf course & decorative ponds
  • Landfill cells, covers, & caps
  • Wastewater lagoons
  • Secondary containment cells/systems
  • Liquid containment
  • Environmental containment
  • Soil Remediation
