Pre-applied HDPE membrane is a widely used material

The pre-applied HDPE membrane is a waterproof and impermeable material. It is a plastic film made of hdpe plastic particles by lamination or blown film process. The pre-applied HDPE membrane is suitable for high requirements on waterproof performance, acid and alkali resistance, corrosion resistance and aging resistance. It is the choice for other anti-seepage projects such as chemical ponds, sewage ponds, landfills, fish ponds, and ash fields.

The pre-applied HDPE membrane also has good heat and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, resistance to environmental stress cracking and tear strength, mechanical properties and barrier properties will increase with increasing density, heat resistance, and tensile strength Also high; can resist acid, alkali, organic solvent and other corrosion.
It can be seen that the pre-applied HDPE membrane is a polymer chemical flexible material with a small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and freezing resistance. Permeable waterproof material.
This pre-applied HDPE membrane can not only be used alone, but also can be compounded with non-woven geotextiles through equipment to form composite geotextiles. Anti-seepage, tensile, acid and alkali resistance and other characteristics, in water conservancy, municipal, construction, transportation, subway, tunnel, engineering construction of anti-seepage, reinforcement, anti-cracking and other civil engineering needs. Pre-applied HDPE membrane is a composite anti-seepage material that is widely used at present. It plays an important role in the anti-seepage treatment of dams and drainage ditches, and the anti-fouling treatment of waste yards.
