Product Introduction
LLDPE geomembrane (linear low-density polyethylene geomembrane) is a waterproof and anti-seepage material made from linear low-density polyethylene (LLDPE), and is widely used in environmental protection, water conservancy, municipal, agricultural and other fields. The following are its key features and applications:
Material properties
LLDPE resin: It is copolymerized from ethylene and a small amount of α -olefins (such as butene and hexene), with a linear molecular chain structure. It combines flexibility and high mechanical strength.
Performance advantages:
Strong puncture resistance: It is more resistant to being pierced by sharp objects than ordinary LDPE (low-density polyethylene).
Good ductility: High elongation at break, adaptable to foundation deformation.
Chemical stability: Resistant to acids, alkalis, salts, oils and most organic solvents.
Low-temperature adaptability: Maintains flexibility in low-temperature environments (-60℃ to 60℃).
Environmentally friendly and non-toxic: Complies with drinking water and soil protection standards.

Application Scenarios
LLDPE Geomembrane Applications in Water Conservancy Projects
1. Reservoir Anti-Seepage
Primary Function: Minimizes water loss through evaporation and seepage, ensuring efficient water storage.
Key Benefits:
Lightweight & Flexible: Easy to install over expansive or irregular surfaces (e.g., artificial lakes, irrigation ponds).
Durability: Resists UV degradation and thermal expansion, even in extreme climates.
Case Example: A Middle Eastern desert reservoir utilized 1.0mm LLDPE geomembrane, maintaining structural integrity after 10 years at 50°C+ with no signs of cracking or aging.
2. Irrigation Channel Seepage Control
Primary Function: Prevents water leakage, improving irrigation efficiency and conserving resources.
Key Benefits:
Easy Welding & Installation: Can be seamlessly spliced along channel lengths.
Terrain Adaptability: Conforms to uneven surfaces without rupturing.
3. Riverbank & Channel Rehabilitation
Primary Function: Stabilizes permeable riverbeds and reduces soil erosion.
Key Benefits:
Composite Reinforcement: When paired with geotextiles, enhances scour resistance and prolongs service life.
Case Example: A Yangtze River slope protection project combined LLDPE geomembrane with geotextile, significantly improving erosion resistance and long-term stability.
