1.5mm thickness provides industry-leading <1×10⁻¹³ cm/s permeability
Virgin HDPE resin with 2.5-3% carbon black ensures complete fluid/gas containment
Unmatched Welding Reliability
Dual smooth surfaces enable perfect heat fusion (hot wedge/extrusion welding)
Consistent 2.0mm weld seams achieve 90% parent material strength
Heavy-Duty Mechanical Properties
Tensile strength ≥30kN/m (MD/XD) withstands earth pressures
Puncture resistance ≥300N (ASTM D4833) for demanding substrates
700% elongation accommodates ground settlement
Introduction:
The HDPE double smooth geomembrane 1.5mm is manufactured from virgin high-density polyethylene resin using advanced three-layer co-extrusion blown film technology, featuring dual smooth surfaces and uniform thickness. Specifically designed for high-standard impermeability projects, this product is particularly suitable for potable water reservoirs, wastewater treatment plants, tunnel waterproofing, and other applications demanding stringent welding quality requirements.
Core Advantages
1. Exceptional Impermeability Performance
Permeability coefficient <1×10⁻¹³ cm/s, completely blocking liquid and gas penetration
1.5mm reinforced thickness provides 50% better impermeability reliability compared to standard 1.0mm products
2. Perfect Welding Performance
Double smooth surface ensures hot wedge welding (dual-track welding) with seam strength reaching over 90% of parent material
30% faster welding speed, significantly reducing construction costs
3. Superior Mechanical Properties
Tensile strength ≥30kN/m (MD/XD), elongation at break ≥700%
Puncture resistance ≥300N (ASTM D4833 standard)
4. Long-Term Durability
Contains 2.5-3.0% premium carbon black, passes 5000kJ/m² UV aging test
Maintains stable performance in extreme temperatures from -60℃ to +80℃
