HDPE Geomembrane Liner 0.5mm 0.75mm 1.0mm 1.5mm 2.0mm

Geomembranes use plastic movies as anti-seepage substrates, commonly which encompass polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt combo geomembrane) is moreover designed and used.

Description

Introduction

HDPE Geomembrane is a impermeable polymer liner and the largest type of geosynthetics.

HDPE Smooth Geomembrane contains approximately 97.5% polyethylene, 2.2% carbon black and trace amounts of antioxidants and heat stabilisers. It has outstanding chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability and thermal aging characteristics.

HDPE textured geomembrane is treated with spray roughening process on the surface of smooth geomembrane, which can greatly increase the engineering adaptability of geomembrane. Its mechanical properties are consistent with the HDPE smooth geomembrane and meanwhile it is of an outstanding direct shear friction coefficient.
