Product Category

HDPE Geomembrane

Product Introduction

HDPE geomembrane (high-density polyethylene geomembrane) is a waterproof and anti-seepage material made by blowing or calendering process. It has excellent anti-seepage performance, chemical corrosion resistance, aging resistance and mechanical strength, and is widely used in anti-seepage projects such as landfills, reservoirs, artificial lakes, sewage treatment pools, and mine tailings ponds.

Features:

High strength: High-strength HDPE material is used, with high tensile strength and can withstand large loads.
Corrosion resistance: HDPE material has good acid and alkali resistance and chemical corrosion resistance, and is suitable for various complex geological environments.
Anti-aging: After special treatment, it has good UV resistance and oxidation resistance, and has a long service life.
Light weight: Light specific gravity, easy to transport and lay, can effectively reduce construction costs.
Convenient construction: Foldable, easy to transport and lay, high construction efficiency.
Good water permeability: Mesh structure, good water permeability, can effectively remove moisture from the soil, and prevent water accumulation from damaging the project.
Ecological and environmental protection: Recyclable and pollution-free.

FAQ:

How long is the service life of HDPE geomembrane?
When used under normal conditions, the service life of HDPE geomembrane can reach more than 50 years. If exposed to strong ultraviolet rays for a long time, the service life will be shortened, but the addition of antioxidants and UV stabilizers can significantly extend the service life.

Is HDPE geomembrane resistant to chemical corrosion?
Yes. HDPE geomembrane has excellent chemical stability and can resist corrosion from most acids, alkalis, salts, oils and organic solvents, and is particularly suitable for chemical and mining environments.
What is the difference between HDPE geomembrane and LLDPE geomembrane?
HDPE film is harder and has high tensile strength, which is suitable for long-term projects;
Is HDPE geomembrane environmentally friendly?
Yes. HDPE is a recyclable material, non-toxic and harmless, and is widely used in environmental protection projects such as landfills and sewage treatment plants, which can effectively prevent pollutants from leaking.
How high a temperature can HDPE geomembrane withstand?
The temperature resistance range of HDPE geomembrane is roughly -60℃ to +60℃. It can withstand higher temperatures for a short time, but long-term high temperatures may affect its performance.
