As for geomembrane performance, the above answers are all to the point. The most important is new material and product performance index is the key.
HDPE geomembrane : ① excellent chemical resistance (corrosion resistance); ② outstanding ability of stress cracking resistance (environmental stress cracking resistance ); ③ lowest permeability; ④ excellent UV resistance; ⑤ stable vertical performance at low temperature; composite geo-membrane performance: Composite geo-membrane (composite anti-seepage membrane )is divided into one cloth and one membrane, two cloth and one membrane, 4-6m wide range , 200-1500g / m?. physical and mechanical property indexes such as tensile, tear, bursting resistance are high. The product has high strength, good extensibility, large modulus?of?deformation, acid and alkali resistant, anti-corrosion, anti-seepage property. It can meet the needs of seepage prevention, insulation, reinforcement abd anti-cracking fixing in water?conservancy, municipal engineering, construction, transportation, subways, tunnels and so on. Because it uses high polymer material and adds antioxidant during production process, it can be used in unconventional temperature environment. It is commonly used in seepage-proof treatment in dams, drainage ditch and antifouling treatment in waste storage.
