Polyethylene(PVC) geomembrane, as a high-performance waterproof and impermeable material, has many remarkable advantages. Thickness: 0.1mm-3mm Width: 2m-6m Color: Black/White/Other colors Following is our PVC geomembrane Thickness 1.6mm specifications: Tensile Strength (vertical and horizontal): 20MPa/mm Elongation at Break (vertical and horizontal): 580% Right-angle tearing strength (vertical and horizontal): 180N/mm Water vapor permeability coefficient: Using temperature range: +70~ -70 Puncture strength 360N Water impervious: 100% Root resistance: 100% Difference Between PVC Geomembrane and HDPE Geomembrane PVC geomembrane and HDPE geomembrane have significant differences in physical properties, treatment difficulty, joint treatment, puncture resistance, and resilience to deformation. Physical Properties and Suitable Environment: PVC membrane: relatively soft and easy to bend, suitable for general waterproofing projects, swimming pools, and wastewater treatment, etc. HDPE membrane: has higher strength and wear resistance, suitable for engineering projects with higher strength and durability requirements, such as water conservancy projects and landfills. Handling Difficulty: PVC membrane: Due to its flexibility, we can make seams in controlled factory conditions, typically requiring fewer on-site seams than HDPE geomembrane. HDPE membrane: Handling in cold weather conditions can be challenging and requires sewing outdoors. Puncture Resistance: PVC membrane: It is harder to penetrate than HDPE and has high elongation characteristics, allowing it to adapt to site changes without reinforcement. HDPE membrane: While it has elasticity, it becomes plastic after exceeding its yield point and no longer has elasticity. Deformation Recovery: PVC membrane: Most of the deformation can be recovered, with a high tensile elongation, suitable for engineering projects with larger design strain limits. HDPE membrane: Deformation after exceeding the yield point cannot be recovered, and the material properties will change. We should select the appropriate geomembrane according to the specific project requirements and the use environment. HDPE geomembrane is suitable for projects that require high strength and durability, while PVC geomembrane is suitable for general waterproofing projects and water treatment.

Hdpe geomembrane are produced from prime hdpe resins result in a high quality premium grade, flexible geomembrane. Overall features & benifits 1. Low permeability - hdpe lining systems are secure because leachate does not Penetrate them; methane gas will not escape from the hdpe cover system; and Rainwater will not infiltrate an hdpe cap. 2. Chemical resistance - hdpe, resistant to a wide range of chemicals, is not threatened by typical solid or hazardous waste leachates. It is also suitable for sludge and secondary containment around chemical storage facilities. 3. Ultraviolet resistance - hdpe's resistance to uv exposure is further enhanced by the addition of carbon black. Additionally, with the absence of plasticizers, volatilization is not a problem. 4. Reflective factor - geotec offers its hdpe geomembrane in white as well as black. A white surface helps mitigate liner According to customers' needs

OSO Geomembrane Liner series offer excellent chemical resistance as well as great physical, mechanical and endurance properties, and meeting GRI GM-13 standard specification for geomembrane liner requirements. Specification Surface: Smooth, Textured Thickness: 0.2mm-0.3mm Width:2m-8m Color: Black, Green, Blue and White Material: HDPE, LDPE, LLDPE Application protection and sanitation, water conservancy projects,municipal engineering, gardens, petrochemical industry, mining industry, traffic facilities, agriculture, aquaculture industry, salt industry
