The difference is that the raw materials to produce geomembrane are different, and the flexibility is also different.
PE geomembrane is of high density.
PE geomembrane is made by processing ethylene raw material. PVC geomembrane is made by processing polyvinyl chloride raw material. Domestic projects nowadays all use the former one which is environmentally friendly, non-toxic, anti-aging, corrosion resistance, and strict national standards have been developed.
