1. Good flexibility
2. For service temperature range:-70°C~110°C
3. Corrosion resistance, aging resistance
4. Excellent environmental stress cracking resistance property
5. High tensile strength and elongation
HDPE smooth geomembrane is produced from high density polyethylene resin by film-blowing process, adding carbon black, antioxidant, anti-aging and UV-resistance component. Now it is the most widely used products for solid waste containment (such as landfill liners), mining and water containment applications.
