High Density HDPE Geomembrane Dam Liner ASTM Standard Anti UV Anti Seepage
Anti UV Anti Seepager ASTM Standard HDPE Geomembrane DAM LINER SUPPLIERS
Yixing Shenzhou HDPE Geomembrane
HDPE geomembrane is made of high density polyethylene resin by film-blowing process, adding carbon black, antioxidant , anti-aging and UV-resistance component and 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.(model according to the thickness of distinction, different thickness and different price) production capacity: thickness:0.1mm -3mm, width: 1-8 meters. It is suitable for seepage control in special industries, and is widely used for aquaculture, seepage control, reservoirs or sewage treatment ponds.
