Chemical And Corrosion Resistant HDPE Geomembrane For Anti-Seepage Needs
Product Introduction
Columnar geomembrane is a geomembrane with uniform protrusions on one or both sides. The membrane surface columns are formed by a special mold pressing roller, resulting in an even and aesthetically pleasing distribution of columnar points.
Product Properties:
High Coefficient of Friction
Customizable Double-Sided Properties
Good mechanical properties
Strong Tensile, Abrasion, and Puncture Resistance
Structurally fluffy and resistant to burial and corrosion
Good environmental adaptability
Outstanding temperature adaptability
Weather resistance and anti-aging properties
Chemical Resistance and Environmental Stress Cracking Resistance
Root Plant Resistance
Product Application
It is widely used in the anti-seepage of domestic waste landfills, solid waste landfills, Sewage Treatment and artificial lakes, tailings treatment and other anti-seepage works.
