Key Features of LDPE Geomembranes
1). High Flexibility
- Soft and pliable, making it ideal for uneven surfaces or projects requiring contour adaptability.
- Maintains flexibility even at **low temperatures** (down to **-50°C**).
2). Chemical Resistance
- Resists mild acids, alkalis, and salts, though less robust than HDPE in harsh chemical environments.
3). Ease of Installation
- Lightweight and easy to weld (using heat or solvents), reducing labor and time costs.
4).Waterproofing Performance
- Provides excellent moisture and water barrier properties for low- to medium-stress applications.
5). Cost-Effective
- Generally cheaper than HDPE, making it suitable for budget-conscious, non-critical projects.
Application Scenarios
- Agricultural: Irrigation ponds, water retention systems.
- Landscaping: Decorative ponds, garden liners.
- Civil Engineering: Secondary containment liners, temporary erosion control.
- Roofing: Underlayment for waterproofing.
- Environmental: Light-duty waste covers or liners (non-hazardous).
