Description(Pass the high pressure OIT)
HDPE geomembrane is also called high-density polyethylene anti-seepage geomembrane. It is a kind of waterproof material, the raw material is high molecular polymer. Generally speaking, the main components are 97.5% HDPE and 2.5% carbon black, antioxidants, anti-aging agents, antioxidants, ultraviolet absorbers, stabilizers and other auxiliary materials. Three-layer co-extrusion blow molding process with automatic equipment is adopted. 1.5mm HDPE geomembrane is generally used in landscape artificial lake seepage prevention, sanitary sewage treatment plant seepage prevention, landfill seepage prevention, highway and railway roadbed reinforcement, retaining wall reinforcement, highway maintenance, water conservancy slope protection, reservoir seepage prevention, etc.
