HDPE Smooth Geomembrane for Seepage Prevention Drainage and
Protection in Various Field
Product Introduction
Smooth surface geomembrane is an important building material,
belonging to one of the geosynthetics. It is mainly used in
engineering projects such as impervious, isolation and
reinforcement. It is made from high-density polyethylene (HDPE) as
the main raw material, with a certain amount of carbon black,
antioxidants, anti-aging agents, ultraviolet absorbers and color
masterbatches added through a special formula. It is then
mass-produced by a highly automated process using a three-layer
co-extrusion blow molding technology.
Physical characteristics
The smooth surface of the light-face geomembrane has good
reflective ability and heat resistance. In addition, the light-face
geomembrane has strong tensile strength and corrosion resistance,
which can maintain its original performance and appearance for a
long time.
Chemical Properties
The smooth surface geomembrane has extremely low permeability,
excellent chemical resistance and UV resistance, which enables it
to maintain good performance in various harsh environments.
Green Features
Smooth geomembrane has excellent environmental protection
performance. High-quality native plastics and carbon black
particles do not contain any preservatives, do not pollute water
quality and soil. In addition, smooth geomembranes can be recycled
and reused, reducing pollution to the environment.
Product Application
Smooth surface geomembrane can be used for seepage prevention,
drainage and protection in water conservancy projects to improve
the waterproof performance and stability of the project. In
environmental protection projects, it can be used for seepage
prevention and protection of landfill sites, sewage treatment
plants and other places to reduce pollution to the environment. In
the field of construction, it can be used for waterproof and
protection of roofs, basements, swimming pools and other places to
improve the service life and safety of buildings.
