What are the raw materials of geomembrane？ The main raw material of geomembrane is high-density polyethylene (HDPE). HDPE is a thermoplastic polymer material formed by polymerization of ethylene monomers, with the following characteristics: High density: HDPE has a high molecular weight and density, which gives the geomembrane good mechanical strength and tensile resistance, and can […]

Anti-seepage principle of geomembrane Physical isolation: Geomembranes have high sealing and anti-seepage capabilities, which can form a physical barrier that effectively prevents moisture, gas or other liquids from penetrating through soil or rock layers and entering the area below. Geomembranes have low permeability through their own material properties, such as high-density polyethylene (HDPE), which reduces

Definition of Geomembrane Geomembrane is an artificial film material used for isolation, anti-seepage, anti-corrosion, reinforcement, etc. between soil and water. It is usually made of high molecular polymers, such as polyethylene (HDPE), polypropylene (PP) and so on. One of the main functions of a geomembrane is to prevent liquids or gases from penetrating into or
