HDPE Geomembrane mit strukturierter Oberfläche

HDPE Geomembrane with textured surface Material: HDPE, ( no odor) Color: black or white Thickness: from 1.0 mm to 2.0mm Width: from 4.0m to 8.0m Roll Length: 50M (or at client’s request). Product description: HDPE geomembrane is a new type of rough surface impervious material, a single rough surface, such as HDPE geomembrane dual rough surface to increase friction coefficient, anti-skid function, more conductive to steep slopes and vertical anti-seepage,thereby improving stability. HDPE has excellent temperature flexibility,good solderability and aging resistance, chemical resistance, resistance to environmental stress cracking resistance and anti-punctured performance. Thus, particularly suitable for underground works,landfills,sewage or waste disposal sites,mining works as anti-leakage materials used.
