Selecting the perfect pond liner for your farm pond is the most important decision while building it. Before selection, one must consider various aspects and parameters for choosing the perfect pond liner, not only in terms of sizes and shapes, but also in terms of the type of material. The two most prominent types of pond liners are HDPE and EPDM.
Material Used
HDPE pond liners are made up of high-density polyethylene plastic, a thermoplastic polymer based on petroleum. An EPDM liner, on the hand, is based on ethylene propylene diene monomer, a flexible synthetic rubber. HDPE pond liners are made of single polymers, while EPDM liners are made of multiple polymers. For a large pond, especially a farm, having a rigid and weldable HDPE liner is much more useful, as EPDM liners, though flexible, cannot be welded.
Affordability
While building large farm ponds, cost plays an instrumental role. HDPE pond liners beat EPDM pond liners hands down in this regard. They cost a lot less, and offer all the features that an EPDM provides, and additionally, HDPE liners also provide protection from UV rays, anti-evaporation, favourable algae growth, and more. By taking multiple factors into consideration, HDPE liners provide a significant value for money against EPDM Liners.
Application
HDPE pond liners provided by Emmbi are as wide as 13.5ft, making them one of the widest liners in the world. Therefore, they are highly useful in building large ponds for agriculture farms, fish farming, rain water harvesting, and more. Moreover, since they are also strong and sustainable with low maintenance, they are perfectly applicable to various other commercial purposes. An EPDM pond liner may not be the ideal choice for a large pond since they cannot be welded. They usually come in smaller sizes, and can only be joined together with adhesives.
Durability – Climatic & Chemical
The HDPE pond liners Emmbi provides are among the strongest in the world, especially in terms of strength and durability. They provide a robust resistance against chemical exposures, UV, and ozone and oxidation. These HDPE liners offer a higher stress cracking resistance, and superior dimensional stability and strength. EPDM liner can’t be repaired if broken whereas HDPE liner is easily repairable by adding sealed patches. EPDM liner has chemical leaching so only suitable for storage of water whereas HDPE pond liner has no chemical leaching and it’s safe for aquatic life.
Recyclability
HDPE Liners are made of polypropylene based on single polymers, which makes them highly recyclable. On the other hand, EPDM is made of multiple polymers, which makes the process of recycling comparatively difficult. The use of welds in HDPE pond liners instead of adhesives also helps make them less toxic to recycle and reuse, whereas recycling EPDM involves chemical process to separate adhesives to recycle the rubberised liners which negatively affects reusability of the liners.
