Supply geomembrane

Geomembrane is a kind of polymer as the basic raw material waterproof barrier materials. Divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane, EVA geomembrane. 1. geomembrane width, thickness specifications complete. 2. Has excellent resistance to environmental stress cracking resistance and excellent chemical resistance. 3. Excellent chemical resistance. 4. Has a large temperature range and long life. 5. Use in landfills, tailings storage sites, channel seepage, dam seepage and underground engineering.
