LLDPE geomembrane
LLDPE geomembrane has high tensile strength, which is usually greater than LDPE. It can withstand greater tensile forces and is less likely to deform or be damaged due to stretching in engineering applications. For example, it can better adapt to complex stress environments in landfill cover systems and other scenarios. And it has stronger puncture resistance, which is very important for application scenarios that may come into contact with sharp objects (such as gravel on construction sites), and can reduce the risk of leakage caused by the puncture of the geomembrane.

Product Description

LLDPE geomembrane, or linear low-density polyethylene geomembrane, is a geosynthetic material with excellent performance.

It has high strength and toughness. Compared with traditional polyethylene materials, it performs better in tensile strength, puncture resistance and other aspects. This enables it to better resist external force damage and ensure the stability and safety of the project in complex engineering environments, such as places with unstable geological conditions and many sharp objects.

It also has excellent resistance to environmental stress cracking. Under long-term external stress and chemical erosion, LLDPE geomembrane is not prone to cracking, which effectively extends its service life.

LLDPE geomembrane has good chemical stability and can resist erosion by a variety of chemicals such as acids, alkalis, and salts. For example, in the treatment of chemical pollution sites, it can effectively isolate harmful substances and prevent their spread.
