Specification :

HDPE geomembrane has excellent resistance to environmental stress cracking performance, large temperature range ( -60 - + 60) and a longer service life ( 50 years)
HDPE geomembrane performance:
1, impermeable good performance: water vapor permeability coefficient K d 1.0 × 10-13? G.cm / c cm2.sp
2, high strength: breaking tensile strength " 28MPa
3, long service life: material life of up to over a hundred years
4, low temperature: cold brittleness temperature of -66  ~ 77 
5, corrosion resistance: the capability of more than 80 species of acid and alkali corrosion
6, non-toxic harmless: the human body is not harmful to the environment, a large number of used water projects abroad.
7, good economic returns: an integrated low cost, low investment
8, the welding performance is good: pad branded welding, weld strength
