Evaluating various membrane types for your next environmental use? Don’t ignore high-density polyethene (HDPE) liner. HDPE has been in use for a long time and over this span a variety of researches have been carried out to test its longevity and capability to satisfy eco-friendly project standards. Here, we explore some of those studies to understand the pros of HDPE in comparison with other geosynthetic membranes such as polyvinyl chloride.
How Does HDPE Stack Up With PVC and Other Geosynthetic Liners?
As a sealing liner, a HDPE geomembrane is chosen over other substances for its modest cost-effective and functional advantage. Cost-wise, HDPE membrane is superior thanks to its fairly simple manufacturing process, which has boosted availability and kept prices down in comparison to other kinds of geosynthetic liners. As more project designers become familiar with the product, increasing competence in its application further promotes its market edge and financial edge over rival materials.
In addition, High-Density Polyethylene is chosen for its material characteristics. Although examinations conducted on Polyvinyl Chloride and HDPE reveal a few practical distinctions, High-Density Polyethylene often does outperform Polyvinyl Chloride and other geosynthetics in aspects such as withstanding bending wear and dynamic impact. Besides, the substance is a exceptionally stable polyolefin that is inert and able to sustain long-term cohesion and strength. These attributes position the HDPE membrane material a preferred choice to impermeabilize and insulate waste disposal sites and other containment systems.
High-Density Polyethylene geomembrane may also be created with additives to enhance certain features.
What ways does the High-Density Polyethylene Geomembrane Aid in Environmental Eco-Friendliness?
Versus other geomembranes, HDPE possesses the highest theoretical unexposed service life at over 100 years. This long-term service capability establishes High-Density Polyethylene a powerful tool for environmental conservation measures such as the secure closure of a dump site.
Concerning unshielded lining, a single study, an HDPE geomembrane enduring a decade of sunlight and wastewater showed no significant change in physical properties (e.g., tensile, tear, puncture, and carbon black ). The only observed difference was in tensile elongation and melt index , both believed to be a result of material cross-linking as a result of UV exposure . However, sunlight exposure over the 10-year period did little to impact most of the material’s properties insomuch that it was nearly indistinguishable from a newly manufactured sample .
The study demonstrates the capable role of HDPE geomembrane in environmental sustainability . Moreover, it suggests that today’s HDPE can be expected to perform at a higher level thanks to technological improvements in resin stabilization and sheet manufacturing techniques .
Using HDPE Geomembranes as a Closure Solution
Seeking the best closure solution for your next sustainability project? Don’t overlook the economic and operational advantages of HDPE geomembrane .
