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
