Geomembrane
Description
HDPE geomembranes provide an impermeable barrier against a wide range of solids and liquids. They exhibit excellent chemical and UV resistance,impermeability, and high yield and welded seam strengths, which is widely used as the liner.
Features
Stable low temperature embrittlement resistance
Outstanding stress crack capacity
Excellent chemical resistance
Excellent UV resistance Lowest permeability
Fast deployment Cost effective
Features
Environmental protection project
Water conservancy project
Gardens golf course
irrigation and aquaculture
