HDPE Geomembrane Price Per Square Meter 1.5mm
HDPE Geomembrane Price Per Square Meter 1.5mm – Technical & Cost Guide
Product Definition
HDPE geomembrane price per square meter 1.5mm refers to the unit-area cost of a 1.5 mm thick high-density polyethylene liner used in environmental containment, offering low permeability, high chemical resistance, and long-term durability for landfill, pond, and industrial lining systems.
Technical Parameters & Specifications
Typical engineering parameters for 1.5 mm HDPE geomembrane used in regulated projects:
| Parameter | Typical Value (1.5mm) | Test Standard |
|---|---|---|
| Thickness | 1.50 mm (-5% tolerance) | ASTM D5199 |
| Density | ≥ 0.940 g/cm³ | ASTM D1505 |
| Tensile Strength (Yield) | ≥ 22 kN/m | ASTM D6693 |
| Elongation at Break | ≥ 700% | ASTM D6693 |
| Puncture Resistance | ≥ 480 N | ASTM D4833 |
| Tear Resistance | ≥ 250 N | ASTM D1004 |
| Carbon Black Content | 2–3% | ASTM D4218 |
| Standard OIT | ≥ 100 min | ASTM D3895 |
These parameters directly influence the hdpe geomembrane price per square meter 1.5mm, particularly tensile strength, resin quality, and antioxidant package.
Structure & Material Composition
Virgin HDPE Resin – Primary impermeable polymer matrix.
Carbon Black (2–3%) – UV stabilization and long-term aging resistance.
Antioxidants – Thermal and oxidative durability enhancement.
Optional Textured Surface – Increased interface friction for slopes.
High-quality virgin resin typically results in higher hdpe geomembrane price per square meter 1.5mm compared to recycled-content alternatives.
Manufacturing Process
Raw Material Feeding – Automated gravimetric blending system.
Extrusion – Flat die or blown film extrusion line with temperature control (200–230°C).
Thickness Calibration – Online gauge monitoring system.
Surface Texturing (if required) – Nitrogen injection embossing.
Cooling & Annealing – Controlled cooling to minimize internal stress.
Rolling & Packaging – Large-width rolls (typically 5–8 m).
Quality Control Testing – Mechanical and OIT verification.
Production efficiency, extrusion line width, and automation level significantly affect the final hdpe geomembrane price per square meter 1.5mm.
