Permeable Material HDPE Smooth Geomembrane For Filtration And Isolation
Product Introduction
The high density polyethylene resin is a waterproof barrier material, which has excellent environmental stress cracking resistance, low temperature resistance, aging resistance and corrosion resistance.
Product Properties
1. It does not contain chemical additives, nor does it undergo heat treatment, and is an environmentally friendly building material.
2. It has good mechanical properties, good water permeability, and can resist corrosion and aging.
3. It has strong buried resistance, corrosion resistance, fluffy structure, and good drainage performance.
4. It has good friction coefficient and tensile strength, and has the performance of georeinforcement.
5. It has the functions of isolation, filtration, drainage, protection, stabilization and strengthening.
6. It can adapt to the uneven base, resist the damage of external construction force, and the creep becomes smaller.
7. Good overall continuity, light weight, convenient construction.
8. It is a permeable material, so it has good filtration isolation function, strong puncture resistance, so it has good protection performance.
Product Application
Mainly used in landfill, sewage waste liquid treatment, water conservancy, agriculture, transportation, high-speed rail, tunnels, airports, airports, buildings, landscape and other anti-leakage liner projects.
