Black hdpe film for waterproof liners

Our high density polyethylene (HDPE) geomembranes present an impermeable barrier against an ample range of solids and liquids. They show excellent chemical and UV resistance, impermeability, and high yield and welded seam strengths, which is widely used as the liner.

Features:

  1. Extensive life, anti-aging, roof material can be more than 20 years, underground can be more than 50 years.
  2. Good tensile strength, high elongation.
  3. Good high/low temperature flexibility
  4. Easy to construct, no pollution.
  5. Good anti-corrosive ability, can be used in special area
  6. Various colors are available

 

Application:

  1. Prevent leakage disposal in waste burying field or waste water or waste dregs disposing Field ,riverbank, lake dam ,mine remaining ,reservoir ,tunnel, liquid storage ,pool(pit, mine)
  2. Preventing leakage in subway, basement, tunnel ,hole
  3. Anti-salt leakage in roadbed and other ground till
  4. The plane direction laying of dam, The vertical direction laying for ground till, Used in the Construction fence and waste material field
  5. Used in seawater or freshwater feed field
  6. Used in ground till of road, highway, railway and waterproof layer of swelling clay and wet collapsed loss Preventing leakage on rooftop.
