Product Introduction
LLDPE (Linear Low-Density Polyethylene) geomembranes represent an advanced class of high-performance anti-seepage barriers engineered through precision polymerization of linear low-density polyethylene resin. The material's molecular architecture features a tightly controlled combination of strategically incorporated α-olefin comonomers (0.5–5.0 wt% branching, typically 1-butene) and a semi-crystalline matrix (35–45% crystallinity), resulting in synergistic enhancements to mechanical strength, impermeability, and environmental durability.
Key Performance Features:
Exceptional Low-Temperature Flexibility
Maintains structural integrity down to -50°C without brittle fracture, validated for arctic-grade engineering applications.Enhanced Anti-Puncture Performance
Incorporates a three-dimensional polyethylene fiber matrix (0.5% vol. reinforcement) via surface modification technology, optimizing stress distribution mechanisms for superior resistance to puncture and abrasion in mining, landfill, and heavy-duty containment systems.Advanced UV Light Stabilization
Engineered with a carbon black loading system (2–3% by mass) that forms a UV-absorbing network, achieving full compliance with ASTM G154 Cycle 1-500 accelerated weathering standards for prolonged outdoor exposure.
Technical Synergy
Through molecular-level engineering of branching distribution and crystallinity, coupled with surface-enhanced polyethylene fiber reinforcement, this geomembrane delivers unmatched performance in permeation resistance (≤1×10⁻¹⁰ cm/s), tensile strength (≥12 MPa), and dimensional stability under thermal cycling (-50°C to 60°C).
Applications
Ideal for critical infrastructure projects including:
Landfill liner/cap systems
Mining leachate containment
Water resource protection (reservoirs, canals)
Industrial waste management

Application Scenarios
Reservoir anti-seepage
Function: Reduce water evaporation and seepage.
Advantages: Lightweight and easy to lay, it can cover large irregular water surfaces (such as artificial lakes and irrigation reservoirs).
Case: A desert reservoir in the Middle East uses LLDPE film (1.0mm thick), which has been operating at a high temperature of 50℃ for 10 years without aging or cracking.
Channel seepage prevention
Function: Prevent the loss of irrigation water and improve the utilization rate of water resources.
Advantages: Convenient welding, can be longitudinally spliced along the channel, and adapt to terrain changes.
River channel management
Function: Repair permeable riverbeds and prevent soil erosion.
Case: A slope protection project along a certain section of the Yangtze River adopted a composite structure of LLDPE film and geotextile, significantly enhancing the anti-scouring capacity.
