Introduction

HDPE dam liner& HDPE Pond liner begins with the melting of the High-density polyethylene resin and the addition of various additives such as antioxidants, plasticizers, fillers, carbon black and lubricants (as processing aids) , used as an impermeable base material. Its impermeable performance mainly depends on the impermeable performance of the geomembrane. At present, the geomembrane used for anti-seepage applications at home and abroad.they are a kind of polymer chemical flexible material with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.


Product features of dam liner& HDPE pond liner

  • Chemical resistance. resistance to high and low temperature, resistance to asphalt, oil and tar, acid, alkali, salt, etc.

  • Outstanding resistance to environmental stress cracking. Elongation at break ≥700%, which can effectively overcome uneven settlement of the base surface.

  • Anti-ultraviolet performance. Anti-aging, anti-ultraviolet, anti-decomposition ability. The life of bare materials can reach 50-70 years.

  • Stable low-temperature drooping performance. Brittleness point below –77 ℃ ~ -90 ℃.

  • Plant root resistance. excellent puncture resistance can resist most plant roots.

  • Environmental protection. The use of environmentally friendly materials make BPM dam liners can resist to ordinary physical changes, which does not produce any harmful substances.
