Flexibility LLDPE Geomembrane
High Chemical Resistance: Excellent durability in harsh environments.
UV & Weather Resistant: Long-lasting performance outdoors.
Superior Puncture Strength: Withstands heavy loads and sharp objects.
Low Permeability: Ideal for effective seepage control.
Flexible Installation: Easy to weld and shape on-site.
Cost-Effective Solution: Long lifespan with minimal maintenance.
Product Introduction
LLDPE is a copolymer of ethylene and a small amount of α -olefins (such as 1-butene, 1-hexene), with its molecular chains linearly arranged but with few branches and uniform distribution. This structure endows it with relatively high tensile strength and tear resistance.
Density range: 0.915-0.940 g/cm³ (between LDPE and HDPE).
Molecular weight distribution: The narrower molecular weight distribution makes its processing performance better and its mechanical properties more stable.

Application Scenarios
Acidic wastewater pool
Function: Isolate acidic mine water in the mine (pH value <3).
Advantages: Resistant to strong acid corrosion (superior to PVC), and can be combined with an HDPE reinforcing layer.
Case: The acidic wastewater pool of a certain copper mine in Chile adopts a composite structure of LLDPE membrane (0.75mm) + bentonite waterproof blanket (GCL).
Anti-seepage of waste rock storage yards
Function: To prevent the spread of tailings dust and the pollution caused by rainwater erosion.
Advantages: Lightweight coverage, reducing soil erosion.
