High Density Polyethylen (HDPE) Geomembrane
Products Description
This product is extruded PE membrane formed by adding anti- oxidant, absorbent of ultraviolet and dyestuff into HDPE and will provide an effective barrier to of liquid water and water vapor.HDPE performs well in mechanical properties ,ageing-resistance , chemical-resistance ,climate- resistance and resistance to puncture
HPDE 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
Solid Waste Landfill for secured dumping of Hazardous Waste.
Lining of Fly Ash ponds.
Thermal / Hydro power plant.
Dumping of Radio Active waste.
Masking of concrete structures at places like Port, Jetty, Bridge.
Spill containment for Chemical and Petrochemical Industries.
