Pond liner (high-density polyethylene geomembrane) is a waterproof material made of high-density polyethylene resin, which is widely used in civil engineering and environmental protection. The following are its main features and applications:
High-density polyethylene (HDPE): has excellent chemical stability, corrosion resistance and UV resistance.
Thickness: usually between 0.2mm and 3.0mm, can be customized according to requirements.
Color: Common colors are black and white, and other colors can also be customized according to requirements.
Features:
Excellent anti-seepage performance: extremely low permeability coefficient, effectively preventing liquid and gas penetration.
Chemical corrosion resistance: can resist erosion by a variety of chemical substances such as acid, alkali, salt, etc.
Anti-ultraviolet: added anti-ultraviolet agent, suitable for long-term outdoor use.
High mechanical strength: excellent tensile, tear and puncture resistance, adaptable to complex terrain.
Environmentally friendly and non-toxic: the material is recyclable and meets environmental standards.
Long service life: under normal use conditions, the service life can reach more than 50 years.
