1. Product Overview
Our pond liners are engineered high-density polyethylene (HDPE) membranes designed for permanent water containment in:
Aquaculture (shrimp/fish ponds)
Agricultural (irrigation ponds)
Landscaping (decorative water features)
Industrial (wastewater lagoons)
Available in 1.0-2.5mm thicknesses with smooth or textured surfaces.
2. Key Performance Metrics
| Property | Test Standard | Specification |
|---|---|---|
| Thickness Tolerance | ASTM D5199 | ±3% |
| Tensile Strength | ASTM D6693 | ≥27 MPa |
| Puncture Resistance | ASTM D4833 | ≥500 N |
| Permeability | ASTM E96 | ≤1×10⁻¹³ cm/s |
| UV Resistance | ASTM D7238 | 20-year warranty |
3. Material Advantages
3.1 Superior Durability
3-layer co-extrusion with UV inhibitors
-60°C to +80°C operational range
Chemical resistance to acids, alkalis (pH 1-14)
3.2 Installation Benefits
Lightweight rolls (easier handling than EPDM)
Wide panels (up to 8m width minimizes seams)
Flexible (conforms to complex pond shapes)
3.3 Ecological Safety
NSF/ANSI 61 certified for potable water
Fish-friendly (no plasticizer leaching)
