Product Introduction

LDPE (Geomembrane) is a geomembrane made of low-density polyethylene (LDPE) and is widely used in civil engineering and environmental protection. Due to its unique physical properties, LDPE geomembrane has become an important material for anti-seepage, waterproofing, isolation and protection.

LDPE geomembrane material features:

Flexibility: LDPE geomembrane is softer than other high-density polyethylene (HDPE) geomembranes, so it is easy to handle during construction and can better adapt to irregular ground.
Corrosion resistance: LDPE geomembrane has strong chemical corrosion resistance and can resist erosion by a variety of chemicals such as acids, alkalis and salts.
Aging resistance: It has good UV resistance, but not as good as HDPE geomembrane, so it may be reduced under sunlight exposure. It is usually recommended to cover the geomembrane with a layer of soil or other covering materials to extend its service life.
Tensile strength and ductility: LDPE geomembrane has good tensile properties and can withstand certain mechanical stress.

LDPE geomembrane application areas:

Landfill: used for the bottom and side walls of landfills to prevent leakage and contamination of groundwater.
Water conservancy projects: such as anti-seepage projects such as pools, ponds, and channels to prevent water leakage.
Agriculture: used in greenhouses or irrigation systems to prevent soil moisture from evaporating or leaking.
Mining projects: used for anti-seepage isolation of mine deposits to prevent harmful substances from entering the environment.
Sewage treatment plants: used for anti-seepage isolation of sewage pools to prevent wastewater from seeping into the ground.

Specifications and performance indicators:

Thickness range: Common thicknesses range from 0.2mm to 2mm, and the specific choice depends on the needs of the application scenario.
Tensile strength: The tensile strength of LDPE geomembrane is generally between 10-20MPa, depending on the product specifications.
Permeability: LDPE geomembrane has excellent anti-seepage performance, and the water permeability coefficient is usually at the level of 10^-11cm/s.
