1. Solar farm waterproofing with reflective surfaces.
2. Tunnel waterproofing with textured slip-resistant layers.
3. Lower installation costs vs. single-layer geomembranes.
Product Introduction:
Haoyang Environmental's breakthrough cold-weather geomembrane combines a specially formulated HDPE layer with a thermally bonded nonwoven composite, delivering unmatched performance in polar environments. The advanced polymer blend maintains 450% elongation at -40°C (ASTM D638) and achieves 98% retained seam strength after 100 thermal cycles between +50°C and -40°C. The 2.0mm composite features:
Low-temperature flexibility: 25mm mandrel bend test compliant at -50°C.
Impact resistance: 8J puncture energy at -30°C (ASTM D746).
UV stability: ≤10% tensile reduction after 5,000hr Arctic UV exposure.
Product Applications:
1. Industrial Process Ponds - Chemical processing and cooling water containment in manufacturing plants.
2. Evaporation Ponds - Solar salt production and mineral concentration facilities.
3. Stormwater Retention Basins - Urban water management systems with combined filtration.
