Weifang Yuanda Polythene Co., Ltd

We manufactures high quality 3-layer co-extruded HDPE, LDPE, LLDPE & EVA geomembranes at large widths and at a thickness of 0,3-2,5 mm. The geomembranes are made from virgin polymers specially selected for their strength and other useful characteristics. They are formulated with fine carbon-black to ensure the maximum lifetime and with antioxidants for protection against thermal degradation. Geomembranes are used in a variety of applications, such as: ?Water reservoirs ?Landfills lining and capping ?Irrigation canals ?Mining ?Highways, dams, lake banks ?Aquaculture ?Pond lining ?Lining of metal tanks HDPE geomembranes are made according to GRI- GM13 international standard at a width of 8 m and at a thickness range of 0,75-3.0 mm. They have the highest strength and chemical resistance. LDPE, LLDPE & EVA liners are made at 0,3-1 mm at widths of 4-14 m (seamless), depending on the thickness. They are more flexible than HDPE, can be made in large widths and are easier to handle. Geomembranes are welded using hot air or hot wedge equipment by specialized installers. Applications Flexible membranes are used in a variety of applications, such as: ?Landfill lining to protect the ground water from contamination. ?Landfills capping to prevent fluid flow in the landfill, to trap and properly vent the gases generated during decomposition of organic waste and to permit efficient revegetation and restoration of the area. ?Water reservoirs for collecting rain-water before it reaches the sea. ?Reservoirs for waste-water to protect the groundwater sources or streams. ?Pond-lining for artificial lakes and irrigation of farms. ?Irrigation canals an economic alternative to concrete and compacted earth for transporting water and irrigating large areas. Also used to reduce seepage from existing deteriorated concrete linings. ?Protection of lake banks for soil stabilization. ?Tunnels protecting the structure against humidity and water pressure
