How to distinguish EVA geomembrane from HDPE geomembrane？

Release time:

2024-03-26

EVA geomembrane: EVA geomembrane is often used in projects that do not have strict soil permeability requirements, such as tunnels, water seepage prevention, waste coverage, lakes, ponds, etc. It can also be used for light applications such as greenhouse covering and rain protection. HDPE geomembrane: HDPE geomembrane is suitable for projects that require high soil permeability, such as landfills, chemical plant sewage tanks, oil tank areas, etc., as well as situations where long-term resistance to mechanical damage and chemical erosion is required.

Material:
EVA geomembrane: EVA (ethylene-vinyl acetate copolymer) geomembrane is a synthetic material made of the copolymer of ethylene and vinyl acetate. Has a smooth, glossy surface with a slight translucency. Compared to HDPE geomembranes, they may appear to be softer, more flexible, and easier to process and install.
HDPE geomembrane: HDPE (high-density polyethylene) geomembrane is made of high-density polyethylene resin, has higher strength and stiffness, and is often harder than EVA geomembrane.

Performance:
EVA geomembrane: EVA geomembrane usually has good weather resistance, chemical resistance and aging resistance, can resist the erosion of ultraviolet rays and oxides, and has good penetration resistance.
HDPE geomembrane: HDPE geomembrane has high wear resistance, tensile strength and impact resistance, can withstand large mechanical stress and extrusion force, and is suitable for projects that require high soil anti-seepage performance.

Application:
EVA geomembrane: EVA geomembrane is often used in projects that do not have strict soil permeability requirements, such as tunnels, water seepage prevention, waste coverage, lakes, ponds, etc. It can also be used for light applications such as greenhouse covering and rain protection.
HDPE geomembrane: HDPE geomembrane is suitable for projects that require high soil permeability, such as landfills, chemical plant sewage tanks, oil tank areas, etc., as well as situations where long-term resistance to mechanical damage and chemical erosion is required.
