HDPE geomembrane is a plastic coil composed of HDPE, which is a highly crystalline, non-polar thermoplastic resin. The appearance of HDPE in its original state is milky white, with a certain degree of translucency in the micro-thin cross-section. HDPE film has excellent impact resistance, so it is so at room temperature and even at a low temperature of -40F. HDPE film is a polymer non-toxic, tasteless, odorless white granules with a melting point of about 110℃-130℃ and a relative density of 0.918- 0.965; with good heat and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear strength properties, with the rise in density, mechanical properties and barrier properties will increase accordingly, heat resistance, and tensile strength is also higher; can be resistant to acids, alkalis, organic solvents and other corrosion.
Geomembrane can meet the civil engineering needs of water conservancy, municipal, construction, traffic, subway, tunnel, engineering construction of seepage control, isolation, reinforcement, anti-cracking reinforcement, etc.. It can be used in unconventional temperature environment because it is made of polymer material and the anti-aging agent is added in the production process. It is commonly used for impermeable treatment of dikes, drainage ditches, and anti-fouling treatment of waste sites.
Geomembrane is characterized by high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good impermeability.
