Chinese top HDPE Geomembrane for dam lining
Product Description
hdpe geomembrane is a waterproof membrane made by polyethylene (PE), PVC
and other geomembranes. After the processes of calendering, spreading and rolling you will
get the product.
Product Features
• Versatile sealing applications possible
• Excellent chemical resistance due to selected raw materials
• Extreme high elongation during uni-axial and multiaxial deformation
• High stress cracking resistance
• Very high UV-resistance
• Direction independent shear stress transfer with structured surfaces
• High interface friction angles with embossed structured surfaces
• Slope dependent structured surfaces available for project specific designs
• Complete quality control from the resin to the final product
• High Melt Flow Index allows an excellent welding performance
• Smooth edges with removable plastic tape for clean welding surface and overlap lines
• ISO 9001: 2000 certified
