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.
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.
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).
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).
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).
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).
