Chemical Resistance of Geomembranes The chemical resistance of a geomembrane refers to its ability to remain stable and undamaged when exposed to different chemicals. Since the geomembrane may be exposed to various chemical substances in actual use, such as acids, alkalis, solvents, etc., its chemical resistance is very important. Generally speaking, the polyethylene (PE) material

What is the stiffness of geomembrane？ The stiffness of geomembranes is usually described by stiffness index or deflection. Stiffness index is a quantitative parameter of bending stiffness of a material under certain conditions, usually expressed in K value, and the unit is m⁴/N. Deflection refers to the degree to which a material bends when an
