1. What Is an HDPE Liner?
An HDPE liner is a geomembrane made from high-density polyethylene resin, a thermoplastic polymer known for its high strength-to-density ratio, chemical resistance, and impermeability. With a density above 0.94 g/cm³, HDPE liners achieve 99.9% fluid containment, preventing up to 100,000 liters of daily seepage per hectare in landfills or reservoirs. They resist acids, bases, and solvents (pH 2–12), ensuring 20–50-year lifespans in harsh environments. HDPE liners are manufactured via extrusion, producing sheets 3–10 meters wide and 100–150 meters long, typically in thicknesses from 0.5 mm to 3.0 mm.
Key Functions
- Leak Prevention: Reduces groundwater contamination risks by 95% in landfills.
- Water Conservation: Saves 50,000–100,000 liters daily per hectare in reservoirs.
