1) Good weather fastness and dimensional stability.
2) Excellent performance to high and low temperature (-40ºC ~ +80 ºC ), UV resistant and anti-corrosion.
3) Higher tensile strength and better extensibility under normal construction conditions.
4) Easy installation, solid joint, and no environmental pollution.
5) Good rooting penetration resistance.
Application:
1) Roofs, basement, toilet, bridge, underground, tunnel and dam.
2) Industrial and civil building waterproof.
3) Geo-synthetic liner for swimming pool, channels, irrigation system .
4) Especially for projects with high requirements in durability, anti-corrosion and deformation
.
