HDPE Pond Liner 1mm Technical Specification Guide
Product Definition
HDPE Pond Liner 1mm is a high-density polyethylene geomembrane barrier with 1.0 mm nominal thickness, engineered for water containment in aquaculture, irrigation reservoirs, decorative ponds, and industrial wastewater lagoons.
Technical Parameters and Specifications
For engineering-grade applications, HDPE Pond Liner 1mm should comply with widely accepted geomembrane performance standards. Typical technical values are as follows:
| Property | Typical Value (1.0 mm) | Test Standard |
|---|---|---|
| Nominal Thickness | 1.00 mm ±5% | ASTM D5199 |
| Density | ≥ 0.940 g/cm³ | ASTM D1505 |
| Tensile Strength at Yield | ≥ 15 kN/m | ASTM D6693 |
| Elongation at Break | ≥ 700% | ASTM D6693 |
| Puncture Resistance | ≥ 320 N | ASTM D4833 |
| Carbon Black Content | 2.0–3.0% | ASTM D4218 |
| Oxidative Induction Time (Std OIT) | ≥ 100 min | ASTM D3895 |
These parameters ensure the HDPE Pond Liner 1mm delivers long-term impermeability and UV stability in exposed or semi-buried pond systems.
Structure and Material Composition
The structure of HDPE Pond Liner 1mm is homogeneous but precisely engineered:
Virgin HDPE Resin: PE100 or equivalent grade for durability and chemical resistance.
Carbon Black (2–3%): Uniform dispersion for UV resistance.
Primary Antioxidants: Thermal stabilization during extrusion.
Secondary Antioxidants: Long-term oxidative aging resistance.
Optional Surface: Smooth (standard) or textured (for slope stability).
Material purity significantly affects the service life of HDPE Pond Liner 1mm in aquaculture and irrigation reservoirs.
Manufacturing Process
1. Raw Material Feeding and Blending
Automated gravimetric systems control resin and additive ratios.
2. Extrusion Casting
Flat-die extrusion at 200–240°C forms continuous sheets. Online thickness gauges ensure dimensional accuracy.
3. Surface Texturing (If Required)
Embossing rollers create asperities for improved friction on slopes.
4. Cooling and Edge Trimming
Controlled cooling avoids residual stress and thickness deviation.
5. Quality Inspection
Each roll of HDPE Pond Liner 1mm is batch-tested for tensile strength, puncture resistance, density, and OIT.
Industry Comparison
| Material | Durability | UV Resistance | Flexibility | Relative Cost |
|---|---|---|---|---|
| HDPE 1mm | High | Excellent | Moderate | Medium |
| LLDPE 1mm | High | Very Good | High | Medium-High |
| PVC 1mm | Moderate | Moderate | High | Lower |
| EPDM Rubber | High | Excellent | Very High | High |
For large-scale ponds, HDPE Pond Liner 1mm offers a balanced solution between mechanical strength, chemical resistance, and cost efficiency.
Application Scenarios
Aquaculture Farms: Fish and shrimp ponds requiring stable containment.
Agricultural Irrigation Reservoirs: Water storage basins.
Industrial Effluent Lagoons: Process water containment.
Landscape Contractors: Decorative lakes and artificial ponds.
EPC Contractors: Turnkey water infrastructure projects.
HDPE Pond Liner 1mm is commonly selected for pond depths up to 5–6 meters depending on subgrade condition and hydrostatic load.
Core Pain Points and Solutions
1. Puncture from Sharp Subgrade
Solution: Install 300–500 g/m² nonwoven geotextile underlay.
2. UV Degradation in Exposed Conditions
Solution: Ensure verified carbon black dispersion and cover with water or soil where possible.
3. Seam Leakage
Solution: Apply double-track hot wedge welding with air pressure testing.
4. Installation Wrinkling
Solution: Schedule installation during moderate temperature conditions.
Risk Warnings and Avoidance
Avoid recycled-content liners for long-term aquaculture use.
Do not install directly over rocky or uncompacted soil.
Verify roll thickness before deployment.
Consider wind uplift during installation planning.
Procurement and Selection Guide
Define pond size, depth, and hydrostatic pressure.
Confirm regulatory or environmental compliance requirements.
Specify HDPE Pond Liner 1mm mechanical properties in tender documents.
Request third-party laboratory test reports.
Calculate overlap and anchorage trench allowance (typically 5–8%).
Evaluate supplier production capacity and lead time.
Confirm welding equipment compatibility.
Review logistics for roll width (usually 5–8 m).
