Extended width-Geomembranes ready for package & shipment
Advanced Equipment of the plant for Geomembrane |
Introduction : Type GL-1 geomembrane is made from LDPE(LLDPE) resin and additives such as antioxidant and carbon black, etc. It can be widely used for reservoir linings, ditches, roadbeds, dyke and other anti-seepage projects.
Type GL-2 is made from a flexible ethylene ¡§ Cvinyl acetate (EVA) co-polymer. It is a relatively new impermeable product with excellent flexibility and high mechanical properties. EVA is generally easy to weld & its application is mainly in irrigation, tunnel, subway linings, construction projects whose structure is complicated.
Specification: Thickness 0.20mm ¨C 3.0mm Width 4M - 14M
Chracteristics:
- There are two types of the geomembrane ' s surface: smooth and textured. The textured surface has higher friction coefficient which can be used to avoid slide between the two covering layers .
- It is a outstanding product with many excellent characters such as high tensile strength, tear resistance ,puncture resistance.
- Anti-aging, impact brittleness of low temperature resistance, It can be used in the circumstances in the range of £ 60 ¡æ ¡ª 60 ¡æ
- Good flexibility, distortion resistance, stress crack of environment resistance.)
- Erosion resistance, bacteria resistance,chemical stability and no poison
- It can be easily welded by hot wedge and hot wind and is convenient for construction. |
