Geomembrane (also known as impermeable membrane), with a thickness of 0.2-3.0mm and a thickness of more than 0.8mm, also known as waterproof board. High-quality polyethylene native resin is selected. The main component is 97.5% high-density polyethylene and about 2.5% carbon black, anti-aging agent, antioxidant, ultraviolet absorber, stabilizer and other auxiliary materials are made by three-layer mutual aid technology.

Features of Geomembrane

1. High tensile strength, so that it has a high tensile strength to meet the needs of high-standard engineering projects 2. Good chemical stability, can resist the corrosion of strong acid, alkali, oil, is a good anti-corrosion material 3. Good heat resistance and cold resistance, its use environment temperature is high temperature 110 ℃, low temperature -70 ℃ 4. Strong weather resistance, strong anti-aging properties, can be exposed for a long time and maintain the original performance 5. Has strong tensile strength and elongation at break
