Shandong Dingrun New Materials Co., Ltd. brand composite geomembrane is made of filament geotextile or short fiber geotextile and PE geomembrane. It has the characteristics of flat drainage and anti-seepage. The composite geomembrane is divided into a cloth and a film, and a cloth with a width of 4-6m and a weight of 200-1500g/m2. The physical and mechanical properties such as tensile strength, tear resistance and bursting are high, and the product has high strength. , good extension performance, large deformation modulus, acid and alkali corrosion resistance, aging resistance, good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, anti-cracking reinforcement in water conservancy, municipal, construction, transportation, subway, tunnel and engineering construction. Because it uses polymer materials and anti-aging agent is added to the production process, it can be used in unconventional temperature environments.
