LDPE Pond Liners with GRI-GM17 Standard
1.It can last above 80 years
2.Environmentally friendly
Low Density Polyethylene (LDPE) Geomembrane
Products Description
This product is extruded PE membrane formed by adding anti- oxidant, absorbent of ultraviolet and dyestuff into LDPE and will provide an effective barrier to of liquid water and water vapor.LDPE performs well in mechanical properties ,ageing-resistance , chemical-resistance ,climate- resistance and resistance to puncture
LDPE characteristics
· Low permeability
· High ultra violet resistance
· Resistant to wide range of chemicals
· Economical over large project areas
· Lower puncture resistance than other membranes
· High coefficient of linear thermal expansion
· Available in textured finish for increased friction
Applications
Prevent leakage disposal in waste burying field or waste water or waste dregs disposing field
River bank,lake dam,mine remainings ,reservior,tunnel,liquid storage pool
Preventing leakage in subway,basement,tunnel,hole
Anti-solt leakage in roadbed and other groudsill
The plane direction laying of dam,the vertical direction laying for groundsill,used in the construction fence and waste material field.
Used in seawater or freshwater feed field
Used in groundsill of road ,highway,railway and waterproof layer of swelling clay and wet collapsed loess.
