Comparing various geomembranes for your next geosynthetic application? Don’t overlook high-density polyethylene (HDPE) geomembrane. HDPE has been doing use for many years and through that time numerous reports have been conducted to test its longevity and skill to fulfill environmental sustainability project requirements. Here, we explore among those studies to examine some great benefits of HDPE in contrast to other geomembranes types including polyvinyl chloride (PVC).

How can HDPE Match up against PVC and Other Geomembrane Types?
As being a waterproofing liner, a HDPE geomembrane is favored over many other materials for the modest economic and operational advantage. Economically, HDPE geomembrane is superior as a result of its relatively straightforward manufacturing process, which has driven up supply and kept prices lower in contrast to other types of geomembranes. Weight loss design engineers know more about the material, growing competence in the use further promotes its market dominance and economic edge over competing products.

Secondly, HDPE may be favored for its physical properties. While tests are powered by PVC and HDPE show hardly any practical differences, HDPE does have a tendency to outperform PVC and other geomembranes in areas such as effectiveness against folding damage and dynamic impact. Furthermore, the pad is an extremely stable polyolefin that is certainly chemically inert and capable to maintain long-term integrity and sturdiness. These properties make HDPE geomembrane a trendy substitute for waterproof and seal landfills as well as other containment applications.

HDPE geomembrane can also be manufactured with additives to amplify certain qualities.

So how exactly does the HDPE Geomembrane Give rise to Environmental Sustainability?
Weighed against other geomembranes, HDPE has got the highest theoretical unexposed service life at >100 years. This high service life potential makes HDPE a powerful tool for environmental sustainability efforts including the safe closure of the landfill.

Regarding exposed liner, one study, a HDPE geomembrane exposed to 10 years of ultraviolet radiation and wastewater showed no significant alternation in physical properties (e.g., tensile, tear, puncture, and carbon black). The one observed difference was at tensile elongation and melt index, both believed to be due to material cross-linking as a result of UV exposure. However, sunlight exposure on the 10-year period did little to affect most of the material’s properties insomuch it's nearly indistinguishable from a newly manufactured sample.

The study demonstrates the capable role of HDPE geomembrane in environmental sustainability. Furthermore, it implies that today’s HDPE should be expected to perform at the more impressive range because of technological improvements in resin stabilization and sheet manufacturing techniques.
