Anti Seepage 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 Geomembrane is an engineered anti-seepage barrier synthesized via precision polymerization and extrusion processes, utilizing linear low-density polyethylene (LLDPE) resin.
Copolymer Composition: Ethylene polymerized with 0.5–5.0 wt% α-olefins (e.g., 1-butene, 1-hexene) to create a linear configuration with controlled branching.
Tacticity: High syndiotacticity (>65%) ensures uniform molecular arrangement, enhancing crystallinity (35–45%) and mechanical strength.
Branching Distribution: Sparse, evenly spaced short-chain branches (C₄–C₆) reduce intermolecular entanglement while maintaining flexibility.

Application Scenarios
Offshore aquaculture cages
Function: To prevent seawater from corroding the aquaculture net.
Advantages: Anti-biological adhesion (with added copper ions), resistant to salt spray corrosion.
Case: A Norwegian salmon farm uses LLDPE film to wrap net cages, which have a lifespan of over 7 years.
Anti-seepage for ground source heat pumps
Function: To isolate underground fluids from heat exchange pipelines.
Advantages: Wide temperature resistance range (-50℃ to 80℃), resistant to chemical corrosion.
Case: The Ice Island geothermal power station uses LLDPE film as the anti-seepage layer for underground pipes.
