Landfill and Environmental Protection HDPE Smooth Geomembrane with 2.0-3.0% Carbon Black Content and Flexible Durable Design
Flexible and Durable HDPE Smooth Geomembrane for Landfill and Environmental Protection
Product Introduction
Smooth surface geomembrane is an important building material, belonging to one of the geosynthetics. It is mainly used in engineering projects such as impervious, isolation and reinforcement. It is made from high-density polyethylene (HDPE) as the main raw material, with a certain amount of carbon black, antioxidants, anti-aging agents, ultraviolet absorbers and color masterbatches added through a special formula. It is then mass-produced by a highly automated process using a three-layer co-extrusion blow molding technology.
Product Properties
High tensile strength, high tear resistance, good flexural, flexibility, elasticity, adapt to geological uneven settlement, strong acid, alkali, oil corrosion resistance, excellent chemical corrosion resistance, good heat resistance and cold resistance.
Product Application
Smooth geomembrane is widely used in water conservancy, environmental protection, municipal engineering, aquaculture, sewage treatment, tailings dam seepage control, landfill, landscape gardening, and hydraulic engineering, etc. For example, in hydraulic engineering, it can be used for the impervious leakage prevention of reservoirs; in sewage treatment projects, it can prevent sewage seepage.
