HDPE Impermeable membrane has a very high tensile strength,tear strength,elongation at break is very large,wide application

HDPE Impermeable membrane’s chemical stable performance well, with good acid, alkali, salt and other 80 kinds of acid and alkali chemical corrosion resistance performance,and also with good water pressure resistance performance and anti-permeability ability.The product has excellent aging resistance performance, long service life.The product is non-toxic and tasteless, the process of the production and use has no pollution, which belongs to the green environmental protection product

HDPE geomembrane performance The product is high density polyethylene as raw material, plus carbon black, stabilizers, UV absorbers made of impermeable material co-extrusion. Corrosion resistance, aging resistance, chemical pollution, impervious strong, easy welding, construction convenient, is the necessary landfill seepage. Uses Landfills, tunnels, canals, reservoirs, dams, sewage pond, swimming pool, pond ecology, landscape lake, pond aquaculture, and railway and highway projects impervious, waterproof.
