Hdpe Pond Liner Geomembrane

Geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage base material and non-woven fabric. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified asphalt copolymer) is also designed for tunnel applications. Concrete geomembrane), they are a polymer chemical flexible material with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.
