Product performance HDPE geotextile is made of a new geomembrane impermeable, anti-corrosion materials, has been widely used in various impermeable preservation requirements engineering. Impermeable good performance : water vapor permeability coefficient K ≤ 1.0 × 10-13?g.cm/c cm2.s.p Strength: Break longitudinal strength "28MPa Long service life : material life could be as long as 100 years Bears the low temperature: Cold shortness temperature -66 77 Corrosion resistance : the ability to more than 80 species of acid, alkali chemical corrosion, etc. Innocuity : harmless to the human body, not to pollute the environment, widely used drinking-water projects overseas. Good economic results : an integrated low cost, investment Province Good welding properties : pad bake welding, weld high strength Application areas Garbage disposal plant, sewage treatment field, environmentalprotection project and so on petrification, metallurgy; Reservoirs, dams, canals, rivers, lakes and other water; MTR, tunnels, underground storage; Artificial lake, gardens and other attractions; The construction market and other waterproofing works NO.ItemIndicatorsGH-1GH-21Tensile Strength Mpa≥17≥252Break elongation ratio%≥450≥5503Cartesian tear strength N/mm≥80≥1104Silica content%≥25Bears the environment stress dehiscence F20h≥15006200 Oxidation induction time≥207Steam penetration coefficient g.cm/cm2.s.pa≤1.0×10-168-70Low temperature impact embrittlement performance Pass9Dimensional Stability%±3
