High Density Polyethylene (HDPE) is the high density version of PE plastic and is harder and denser than the LDPE, but is less ductile, and lighter than water. Its playing an important role to prevent the air and groundwater pollution. The best thing about the HDPE is that it can be easily moulded and welded together and the use of UV Stabilizers improves its weather resistance. HDPE Geomembrane lives up to the expectations which are demanded in todays world of environmental engineering.
