Product Introduction
LLDPE Geomembrane (Linear Low-Density Polyethylene Geomembrane) is a highly flexible impermeable membrane manufactured from LLDPE resin, engineered for superior seepage control in critical applications across environmental protection, water conservancy, and civil engineering.
Exceptional Anti-Seepage – Ultra-low permeability (≤10⁻¹³ cm/s), ensuring reliable containment of liquids and gases.
Easy Installation – Lightweight and weldable (via hot melt or extrusion welding) with strong, seamless joints.
Long-Term Durability – UV-resistant (when carbon black is added) and immune to microbial degradation, offering a service life exceeding 20 years.
This combination of flexibility, chemical resistance, and longevity makes LLDPE geomembrane an optimal choice for demanding engineering and environmental projects.
