60 mil HDPE Liner
1. Excellent anti-seepage performance
The permeability coefficient is extremely low, almost impermeable and non breathable, effectively preventing the migration of pollutants, suitable for environmental protection and hydraulic anti-seepage scenarios.
2. Chemical corrosion resistance
Especially HDPE material can resist the erosion of strong acids, alkalis, salts, oils and other chemical substances, making it suitable for harsh environments such as landfills and chemical parks.
3. High strength and durability
Strong tensile, tear resistant, and puncture resistant abilities, not easily aged after long-term use
4. Lightweight and efficient construction
Lightweight, easy to transport and lay, construction speed much faster than traditional concrete anti-seepage, greatly shortening the construction period.
Product Introduction:
60 mil HDPE Liner is a waterproof and barrier material made from polymer materials such as polyethylene (PE), polyvinyl chloride (PVC), ethylene/vinyl acetate copolymer (EVA), etc. It is mainly used to prevent water, liquid, or gas from penetrating.
Core performance characteristics
1. Excellent anti-seepage performance:
The water vapor permeability coefficient is as low as 1 × 10 ⁻¹³ g · cm/(cm ² · s · Pa), which can effectively block liquid permeation.
2. Chemical corrosion resistance:
Resistant to over 80 types of chemical media such as acid, alkali, and salt corrosion, suitable for scenarios such as chemical wastewater tanks and tailings ponds.
3. Strong environmental adaptability:
Wide temperature range and excellent frost resistance. Resistant to UV aging, with a lifespan of over 50 years when used in the dark.
4. Outstanding mechanical performance:
Tensile strength ≥ 12MPa, elongation at break ≥ 300%, able to adapt to foundation deformation.
High puncture resistance, able to resist sharp objects such as gravel and tree roots.
5. Construction convenience:
The width can reach 6 meters, reducing the number of welds and lowering the risk of leakage.
Support hot melt welding, with weld strength higher than the base material, ensuring overall sealing.
