pvc geomembrane - xx-geo

HDPE Geomembrane for buildings,subways,tunnels

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.

Thickness: 0.08mm-2.5mm
Width:2.0m-6.0m
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.
