Product Introduction
HDPE membrane is also known as high-density Polyethylene membrane, HDPE geotextile membrane, and HDPE anti-seepage
membrane. Its English name is "High Density Polyethylene Impermeable membrane", and it is simply called "HDPE membrane".
HDPE is a thermoplastic resin with high crystallinity and non-polarity. The original state of HDPE appears milky white and is semi-
transparent to a certain extent in thin sections. HDPE has excellent anti-corrosion performance, electrical performance, moisture-
proof performance, anti-seepage performance and high tensile strength. Therefore, it is very suitable for engineering anti-seepage
aquaculture anti-seepage, oil tank anti-seepage, basement anti-seepage, artificial lake anti-seepage and other fields.
Performance features
1. High anti-seepage coefficient - The anti-seepage membrane has an anti-seepage effect that ordinary waterproof materials
cannot compare with. HDPE anti-seepage membrane has high tensile strength and mechanical properties. Its excellent elasticity
and deformation capacity make it very suitable for expanding or contracting base surfaces, effectively overcoming the uneven
settlement of the base surface. The water vapor permeability coefficient K is <=1.0*10-13 GCM /ccm2spa.
2. Aging resistance - The anti-seepage membrane has excellent anti-aging, anti-ultraviolet and anti-decomposition capabilities.
It can be used exposed and has a material service life of 50 to 70 years, providing a good material guarantee for environmental
anti-seepage.
3. High mechanical strength - The anti-seepage membrane has excellent mechanical strength, with a tensile strength at break
of 28MPa and an elongation at break of 700%.
4. Resistance o plant roots - HDPE anti-seepage membrane has excellent puncture resistance and can withstand the root systems
of most plants.
5. Chemical Stability - Anti-seepage membranes have excellent chemical stability and are widely used in sewage treatment, chemical
reaction tanks, and landfill sites. Resistant to high and low temperatures, asphalt, oil and tar, as well as over 80 kinds of strong acid
and alkali chemical media such as acids, alkalis and salts.
6. Fast construction speed - The anti-seepage membrane has high flexibility, with various specifications and laying forms to meet
the anti-seepage requirements of different projects. It is welded by hot melt, with high weld strength, and is convenient, fast and
healthy to construct.
7. Low cost and high efficiency - HDPE anti-seepage membrane adopts new technology to enhance the anti-seepage effect, but
the production process is more scientific and rapid. Therefore, the product cost is actually lower than that of traditional waterproof
materials. According to actual calculations, general projects using HDPE anti-seepage membrane can save about 50% of the cost.
8. Environmentally friendly and non-toxic - The materials used in the anti-seepage membrane are all non-toxic and environmentally
friendly. The anti-seepage principle is a common physical change, which does not produce any harmful substances. It is an ideal
choice for environmental protection, aquaculture, and drinking water pools.
Function and application
It is mainly applied in anti-seepage lining projects such as landfill, sewage and waste liquid treatment, water conservancy, agriculture,
transportation, high-speed rail, tunnels, airports, buildings, and landscapes.
