High Density Polyethylene Geomembrane
Available in smooth and textured surface, 0.25-3.0mm thick with a maximum of width of 3m, and length according to the requirements. Textured surface films provide great friction resistance. Colored Geomembranes are also available upon request. Textured asperity can also be manipulated to meet project needs.
A linear polymer, High Density Polyethylene (HDPE) is prepared from ethylene by a catalytic process. The absence of branching results in a more closely packed structure with a higher density and somewhat higher chemical resistance than LDPE. HDPE is also somewhat harder and more opaque and it can withstand higher temperatures (120°C for short periods and 110°C continuously.
This is the most widely used geomembrane in the world due to its inexpensive material cost. HDPE lining material is an excellent product for large applications that require UV and Ozone resistance, chemical resistance or high-quality installations. One of the main uses of HDPE is for landfill base liners, Waste lagoons, Pond lining, Aquacultures and mining applications where its chemical resistance is used to good effect. HDPE is best used as an exposed lining material, and has the UV resistance required for many years of outstanding service.
