Nepal FDD lSO Certificate ASTM 0.5mm-2.5mm HDPE Geomembrane Liner for Shrimp Pond Liner

Geomembranes use plastic movies as anti-seepage substrates, commonly which encompass polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt combo geomembrane) is moreover designed and used.

Product Description

Introduction

"Pond liner" usually refers to the liner used at the bottom of a pond, which can play a role in waterproofing, protecting the bottom of the pond, preventing water leakage, and so on. You can consider factors such as material, size, thickness, etc. when purchasing liners to ensure that you choose the appropriate liner for your pond.

Applications

HDPE pond liner is a type of pond liner made from high-density polyethylene (HDPE) as the raw material. HDPE is a material with excellent waterproof performance, chemical corrosion resistance, and wear resistance. HDPE pond liners typically have the following characteristics:

High strength: HDPE material has high tensile strength and impact resistance, and can withstand certain external pressures.
Corrosion resistance: HDPE has strong resistance to chemical corrosion and is suitable for long-term use in ponds.
Good waterproof performance: HDPE material itself has good waterproof performance, which can effectively prevent water leakage in ponds.
Environmental protection: HDPE materials themselves have good environmental performance and have a relatively small impact on the environment during use.
The use of HDPE pond liners can effectively protect the pond structure, prevent water leakage and pollution, and extend the service life of the pond.
