Detailed Product Description

High-Density Polyethylene (HDPE) Smooth Geomembranes represent the pinnacle of fluid containment technology, delivering unmatched hydraulic integrity and long-term environmental protection. Manufactured from premium-grade virgin resins with stabilized carbon black and antioxidants, our smooth geomembranes provide a defect-free, homogeneous barrier solution for demanding applications where zero leakage is non-negotiable.

Core Technical Advantages

  1. Optimal Hydraulic Performance

    • Ultra-Low Permeability: Hydraulic conductivity ≤1×10<sup>-13</sup> cm/sec (ASTM E96).

    • Zero Porosity: Non-textured surface eliminates preferential flow paths.

  2. Superior Chemical Resistance

    • Resists acids, alkalis, hydrocarbons, salts, and landfill leachates (Compatible with >300 chemicals per GRI GM17).

    • Ideal for potable water containment (NSF/ANSI 61 certified).

  3. Enhanced Mechanical Properties

    • Tensile Strength: 28–45 MPa (ASTM D6693 Type IV).

    • Puncture Resistance: >600 N (ASTM D4833).

    • Stress Crack Resistance: >500 hrs (Notched Constant Tensile Load, ASTM D5397).

  4. Long-Term Durability

    • UV Resistance: ≥2.5% carbon black content (ASTM D4218).

    • Thermal Stability: Service range -70°C to +80°C.

    • OIT Retention: ≥80% retained oxidative induction time after 90-day UV exposure (ASTM D3895).

  5. Installation Efficiency

    • Low Friction Coefficient: μ = 0.1–0.15 (ASTM D5321) enables rapid deployment on slopes.

    • Seam Integrity: Fusion seams achieve ≥90% parent material strength (ASTM D6392).

Why Smooth HDPE?

"Smooth HDPE geomembranes provide the lowest permeability and highest chemical resistance among polymeric liners. Their homogeneous structure ensures predictable, long-term performance in critical containment systems where fluid loss risk must be minimized."
— Geosynthetics International (Vol. 29, 2022)
