100% What is the difference between virgin and recycled HDPE geomembranes?

Release time:

2024-08-07

100% virgin HDPE geomembranes differ from recycled HDPE geomembranes in physical properties, raw materials and service life.

Geomembrane is a geotechnical seepage control material made of plastic film as seepage control substrate and compounded with non-woven fabric, which is divided into low density polyethylene (LDPE) geomembrane and high density polyethylene (HDPE) geomembrane. Geomembrane is a kind of high polymer flexible material, with small specific gravity, large extensibility, strong adaptability to deformation, corrosion resistance, low temperature resistance, good frost resistance and other characteristics.

What is the difference between 100% pure material and recycled HDPE geomembrane? 100% pure material HDPE geomembrane is a geomembrane made from 100% pure material HDPE resin granules, while recycled HDPE geomembrane is a geomembrane made from recycled HDPE resin granules. There are many significant differences between these two types of HDPE geomembranes.

Native HDPE geomembrane and recycled HDPE geomembrane differences in raw materials.
Domestic brand pure material HDPE geomembrane raw materials are first of all national brand pure material and imported brand pure material, of which national brand pure material has Sinopec, Yanshan Petrochemical, Qilu Petrochemical, Kunlun Petrochemical, etc., and imported brand pure material has Iranian petrochemicals, Saudi petrochemicals, Bolu Chemical, Nordic Chemical, etc. The raw material of HDPE geomembrane is the recycled granules of high-density polyethylene plastics produced by the domestic or foreign small factories with no brand.

100% virgin HDPE geomembrane and recycled HDPE geomembrane physical property differences
The physical properties of HDPE geomembrane include tensile strength, yield strength, puncture strength, right-angle tear strength, etc. The physical properties of 100% virgin HDPE geomembrane are much higher than those of recycled HDPE geomembrane.

Difference in chemical function between 100% virgin material HDPE geomembrane and recycled HDPE geomembrane
The chemical properties of HDPE geomembrane include crack resistance, aging resistance, sunlight resistance, oil and salt resistance, acid and alkali resistance, corrosion resistance, high temperature resistance, low temperature resistance, and harmlessness, etc. These chemical properties of 100% virgin material HDPE geomembrane are much higher than those of recycled material HDPE geomembrane.

Brand 100% virgin material HDPE geomembrane and recycled HDPE geomembrane between the appearance of the difference between the
Branded 100% virgin material HDPE geomembranes have a lubricated, glossy, and pliable appearance, while recycled HDPE geomembranes have an oily appearance, rough material patches, and poor flexibility.

Brand 100% virgin material HDPE geomembrane vs. recycled HDPE geomembrane service life differences

Branded 100% virgin material HDPE geomembranes have a service life of 50 to 100 years underground, while HDPE geomembranes made from recycled materials have a service life of up to 10 years underground and are not recommended for use above ground.

Brand 100% virgin material HDPE geomembrane and recycled HDPE geomembrane price difference
The price of branded 100% virgin material HDPE geomembrane is generally higher than the price of recycled HDPE geomembrane of the same thickness.

Generally speaking, the civil construction seepage control project with low requirements can use low-priced recycled HDPE geomembrane, such as aquatic feeding seepage control project, lotus root pond seepage control project, cistern seepage control project and so on. Strict environmental requirements for the application of the project, the brand should be used 100% pure material HDPE geomembrane, such as landfill seepage control project, tailings treatment plant seepage control project, septic tank seepage control project, digestion pool seepage control project, oxidation pool seepage control project, petroleum storage tank seepage control project, chemical reaction pool seepage control project and so on.
