The performance characteristics of HDPE geomembrane are as follows:

1. HDPE geomembrane is a flexible waterproof material with a high impermeability coefficient (1×10-17cm/s);

2. HDPE geomembrane has good heat resistance and cold resistance, and its use environment temperature is high temperature 110℃, low temperature -70℃;

3. HDPE geomembrane has good chemical stability and can resist the corrosion of strong acid, alkali and oil. It is a good anti-corrosion material;

4. HDPE geomembrane has a high tensile strength, so that it has a high tensile strength to meet the needs of high-standard engineering projects;

5. HDPE geomembrane has strong weather resistance, strong anti-aging performance, and can be exposed for a long time while maintaining the original performance;

6. The overall performance of HDPE geomembrane. HDPE geomembrane has strong tensile strength and elongation at break, which enables HDPE geomembrane to be used under various harsh geological and climatic conditions. Adapt to uneven geological settlement, strong strain;

7. HDPE geomembrane is made of high-quality virgin plastic and carbon black particles do not contain any preservatives. HDPE has been used in my country to replace PVC as a raw material for food packaging bags and cling film.
