Excellent Flexibility and Elongation: PVC material inherently possesses a very high break elongation (typically >200%), allowing it to accommodate foundation settlement and deformation without cracking.
Superior Puncture Resistance: The 0.75-mm thickness provides good mechanical strength, effectively resisting penetration by sharp objects like gravel or roots on-site.
Outstanding Fluid Barrier Properties: Its dense molecular structure results in an exceptionally low permeability coefficient (K ≤ 1×10⁻¹² cm/s), making it an excellent barrier to water and chemical solutions.
Chemical Resistance: The 30 mil (0.75 mm) PVC geomembrane offers good resistance to weak acids, weak alkalis, salts, and certain organic compounds, suitable for most wastewater and environmental containment projects.
Strong Weldability: Seams are created using hot-air welding, producing high-strength, reliable bonds that form a continuous, integrated containment system.
Weather & UV Resistance: Incorporated UV absorbers and stabilizers allow for long-term outdoor exposure with slow performance degradation, resulting in a long service life (design life can exceed 20 years).
Low-Temperature Flexibility: Maintains good flexibility in cold environments (e.g., -20°C or lower) without becoming brittle, making it suitable for use in cold climates.
