Versatile HDPE Geomembrane For Various Anti-Seepage Projects
Product Introduction
HDPE membrane, full name high-density polyethylene membrane, also
known as HDPE geomembrane or HDPE impervious membrane, is a plastic
rolled material made of high-density polyethylene (HDPE) resin.
HDPE membrane has various excellent properties, which make it
widely used in engineering waterproofing field.
Product Properties
♦ Excellent chemical resistance (corrosion resistance);
♦ Outstanding stress cracking resistance (environmental stress
cracking resistance);
♦ Lowest permeability;
♦ Excellent UV resistance;
♦ Stable resistance to low temperature embrittlement;
Product Application
HDPE geomembrane is widely used in many fields due to its unique
properties. In terms of municipal environmental protection, it can
be used for anti-seepage projects such as domestic waste landfill
anti-seepage, solid waste landfill anti-seepage, sewage treatment
plant anti-seepage, artificial lake anti-seepage, and tailings
treatment. In water conservancy anti-seepage projects, HDPE
geomembrane can meet the anti-seepage treatment needs of dams and
drainage ditches, as well as anti-pollution treatment of waste
sites. In addition, it is also suitable for anti-seepage projects
of transportation infrastructure, agricultural water conservancy
anti-seepage projects, aquaculture industry, and other construction
anti-seepage, anti-corrosion, anti-leakage, reinforcement,
collection of leachate, and prefabrication of special components of
temporary container structures.
