geomembrane

Description

Geomembrane Geomembrane is a kind of waterproof material with basic raw material of high molecular polymer. It is mainly divided into LDPE geomembrane, HDPE geomembrane, EVA geomembrance. Features: 1. Excellent environmental stress resistant cracking performance and chemical erosion resistance 2. Big scope of application temperature and long service life . Function:Applied in landfill waste site, sewage and filth treatment site, tailings depot and underground construction project Physical-mechanical property of the geomembrane 　Items Index LDPE geomembrane HDPE geomembrance GH*1 GH*2 Tensile strength MPa ≥*4 ≥*7 ≥*5 Elongation at break% ≥**0 ≥**0 ≥**0 Right angle tearing strengthN/mm ≥*0 ≥*0 ≥**0 Carbon soot quantity ≥2 Environmental stress resistant cracking performance - - ≥***0 Oxidation induction time at **0℃min - - ≥*0 Permeability coefficient of vapor(g•cm/cm2•s•pa) ≤1.0x Scope of application temperature **0℃ï&frac*2;ž**0℃ Oxidation induction time at **0℃ min >*0
