Geomembrane

HDPE Geomembrane
HDPE geomembrane has excellent environmental stress cracking resistance, excellent impermeability, high barrier property, high puncture resistance, corrosion resistance, excellent elongation and wear resistance. It has high tensile strength, outstanding low temperature resistance, high temperature resistance (-70℃~110℃), anti-aging, high tearing strength, good bonding property, and the underground service life can reach 30-50 years.
