Geo-membrane is produced by a method of three layer co-extrusion model. The raw material is processed at 200°C by fusing and coextrusion, whose basic properties are kept during the producing process. Material: HDPE Thickness: 0.08mm-2.5mm Width:2.0m-7.0m Quality Inspection Standard: GB/T17643-1998 Quality Control Measure: strictly comply with ISO9001:2000 Have passed the CE certificate in Sep. 2008. Features: 1) Can bear chemical erosion. 2) A wider using temperature range and a longer using life. Application: It can be widely used in areas of garbage burying, waste disposal, tail minerals storage and underground construction projects.
