Product Introduction
LLDPE geomembrane, a linear low-density polyethylene-based impermeable material, finds extensive applications in civil, hydraulic, and environmental engineering. It exhibits strong resistance to chemical corrosion (including acids, alkalis, and salts) and retains flexibility even at extremely low temperatures (-50°C), making it suitable for cold climates. However, its UV resistance is limited (requiring stabilizers for prolonged outdoor use), and its low density (0.915–0.940 g/cm³) ensures lightweight and easy installation.
