Geomembrane 0.75mm HDPE Liner

I. Introduction

      0.75mm HDPE Geomembrane Liner is a high-performance anti-seepage material made from high-density polyethylene resin. It is widely used in environmental protection, water conservancy, aquaculture, landfill, chemical anti-corrosion and other projects. With moderate thickness, stable performance and high cost performance, it has become one of the most commonly used specifications in anti-seepage engineering. It provides reliable waterproof and anti-pollution functions, effectively ensuring project safety and service  life.

 II. Product Composition and Production Process

     This geomembrane is produced by advanced extrusion or blow molding process, using high-quality HDPE raw materials with added antioxidants, UV stabilizers and carbon black. These additives enhance aging resistance and durability. Strict control of raw material ratio, temperature and pressure during production ensures uniform thickness, stable performance and reliable quality. The 0.75mm thickness balances flexibility and strength, making it suitable for various complex working conditions.

IV. Anti-seepage Performance

     Anti-seepage is the core function of 0.75mm HDPE Geomembrane. Its permeability coefficient is as low as 1×10⁻¹³ cm/s, which can form an effective waterproof barrier. It completely blocks the penetration of water, sewage, leachate and chemical liquids, preventing groundwater and soil pollution. It meets strict environmental protection and waterproof standards, and is widely used in landfill, sewage pool, pond and reservoir projects.

V. Mechanical Properties

     0.75mm HDPE Geomembrane has excellent mechanical performance. High tensile strength and elongation at break allow it to adapt to foundation deformation and settlement without cracking. High tear resistance and puncture resistance reduce damage during transportation and construction. Good mechanical stability ensures long-term safe use under pressure and external impact.

VI. Aging Resistance and Environmental Adaptability

     With special antioxidants and UV stabilizers, this geomembrane has strong aging resistance. It can maintain performance for a long time in outdoor exposure, not easy to harden, brittle or crack. It has good resistance to acid, alkali, salt and other chemical corrosion, and can work stably in harsh environments. Wide operating temperature range ensures normal use in cold and hot areas.

VII. Construction Method and Application Scope

     0.75mm HDPE Geomembrane is lightweight and flexible, easy to cut, weld and lay. Hot wedge welding and extrusion welding form a sealed whole, ensuring overall anti-seepage effect. It is widely used in landfill liners, sewage treatment tanks, fish and shrimp ponds, reservoirs, canals, chemical anti-corrosion pools, roof gardens and other anti-seepage projects. Easy construction and low cost make it popular in many engineering fields.

VIII. Conclusion

     0.75mm HDPE Geomembrane Liner has excellent anti-seepage, mechanical, aging-resistant and corrosion-resistant properties. Complete technical parameters, stable quality and convenient construction make it widely used in various anti-seepage and waterproof projects. It is a reliable, economical and practical anti-seepage material, providing strong support for engineering quality and long-term operation.
