Compared with HDPE geomembrane, LLDPE features outstanding flexibility, high elongation at break and excellent low-temperature resistance. It adapts well to differential foundation settlement and irregular subgrade without easy cracking. It delivers zero water permeability and good acid-alkali chemical resistance, and can be hot-welded on site. Common thickness ranges from 0.5mm-2.0mm, popular sizes: 0.5mm, 0.8mm, 1.0mm, 1.5mm, roll width 2-6m. Smooth surface is standard.<\/p>\n<h2>Key features<\/h2>\n<ul>\n<li>Ultra-high elongation accommodates differential settlement and soft-ground movement<\/li>\n<li>Retains flexibility in low-temperature environments with reduced brittle-cracking risk<\/li>\n<li>Soft sheet conforms closely to curved, irregular and complex basin geometry<\/li>\n<li>Non-toxic formulation suitable for aquaculture and water-containment projects<\/li>\n<li>Compatible with hot-wedge and extrusion welding for reliable field seams<\/li>\n<li>UV-stabilized options available for exposed outdoor service<\/li>\n<\/ul>\n<h2>Parameter<\/h2>\n<p class=\"tjsp-parameter-hint\">Swipe or scroll horizontally to view the complete table.<\/p>\n<div class=\"tjsp-parameter-scroll\" style=\"max-width:100%;overflow-x:auto;-webkit-overflow-scrolling:touch;margin:22px 0 36px;width:100%\">\n<table style=\"border:1px solid rgba(11,42,58,.14);border-collapse:separate;border-spacing:0;margin:0;min-width:640px;width:100%\">\n<caption>General Required Properties<\/caption>\n<thead>\n<tr>\n<th scope=\"col\">Property<\/th>\n<th scope=\"col\">Unit<\/th>\n<th scope=\"col\">GRI-GM17 Minimum Requirement<\/th>\n<th scope=\"col\">Test Method<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Density<\/td>\n<td>g\/cm\u00b3<\/td>\n<td>0.915-0.939<\/td>\n<td>ASTM D1505<\/td>\n<\/tr>\n<tr>\n<td>Elongation at Yield<\/td>\n<td>%<\/td>\n<td>\u2265 12<\/td>\n<td>ASTM D6693 (Type IV)<\/td>\n<\/tr>\n<tr>\n<td>Elongation at Break<\/td>\n<td>%<\/td>\n<td>\u2265 800<\/td>\n<td>ASTM D6693 (Type IV)<\/td>\n<\/tr>\n<tr>\n<td>Carbon Black Content<\/td>\n<td>%<\/td>\n<td>2.0 \u2013 3.0<\/td>\n<td>ASTM D4218 \/ D1603<\/td>\n<\/tr>\n<tr>\n<td>Carbon Black Dispersion<\/td>\n<td>Rating<\/td>\n<td>Max Grade 3<\/td>\n<td>ASTM D5596<\/td>\n<\/tr>\n<tr>\n<td>Multiaxial Elongation<\/td>\n<td>%<\/td>\n<td>\u2265 30<\/td>\n<td>ASTM D5617<\/td>\n<\/tr>\n<tr>\n<td>Stress-Crack Resistance (SP-NCTL)<\/td>\n<td>h<\/td>\n<td>\u2265 500<\/td>\n<td>ASTM D5397<\/td>\n<\/tr>\n<tr>\n<td>Standard OIT<\/td>\n<td>min<\/td>\n<td>\u2265 100<\/td>\n<td>ASTM D3895<\/td>\n<\/tr>\n<tr>\n<td>High-Pressure OIT (HP-OIT)<\/td>\n<td>min<\/td>\n<td>\u2265 400<\/td>\n<td>ASTM D5885<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div class=\"tjsp-parameter-scroll\" style=\"max-width:100%;overflow-x:auto;-webkit-overflow-scrolling:touch;margin:22px 0 36px;width:100%\">\n<table style=\"border:1px solid rgba(11,42,58,.14);border-collapse:separate;border-spacing:0;margin:0;min-width:780px;width:100%\">\n<caption>Thickness-Dependent Mechanical Properties<\/caption>\n<thead>\n<tr>\n<th scope=\"col\">Property<\/th>\n<th scope=\"col\">Unit<\/th>\n<th scope=\"col\">0.5 mm<\/th>\n<th scope=\"col\">0.8 mm<\/th>\n<th scope=\"col\">1.0 mm<\/th>\n<th scope=\"col\">1.5 mm<\/th>\n<th scope=\"col\">2.0 mm<\/th>\n<th scope=\"col\">Test Method<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Tensile Yield Strength<\/td>\n<td>kN\/m<\/td>\n<td>8<\/td>\n<td>12.8<\/td>\n<td>16<\/td>\n<td>24<\/td>\n<td>32<\/td>\n<td>ASTM D6693<\/td>\n<\/tr>\n<tr>\n<td>Tensile Break Strength<\/td>\n<td>kN\/m<\/td>\n<td>14<\/td>\n<td>22.4<\/td>\n<td>28<\/td>\n<td>42<\/td>\n<td>56<\/td>\n<td>ASTM D6693<\/td>\n<\/tr>\n<tr>\n<td>Tear Resistance<\/td>\n<td>N<\/td>\n<td>64<\/td>\n<td>102<\/td>\n<td>125<\/td>\n<td>187<\/td>\n<td>249<\/td>\n<td>ASTM D1004<\/td>\n<\/tr>\n<tr>\n<td>Puncture Resistance<\/td>\n<td>N<\/td>\n<td>160<\/td>\n<td>256<\/td>\n<td>320<\/td>\n<td>480<\/td>\n<td>640<\/td>\n<td>ASTM D4833<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>\u041f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u044f<\/h2>\n<ul>\n<li>Fish ponds, shrimp farms, aquaculture reservoirs and decorative lakes<\/li>\n<li>Farm reservoirs, irrigation canals, manure lagoons and biogas floating covers<\/li>\n<li>Landfill caps, secondary liners and temporary containment ponds<\/li>\n<li>Sewage lagoons, sludge drying beds and industrial wastewater basins<\/li>\n<li>Mining evaporation ponds, solution holding ponds and temporary cofferdams<\/li>\n<li>Cold-climate projects, uneven subgrades and irregular excavations<\/li>\n<\/ul>\n<h2>Specification and supply<\/h2>\n<p>Taiji supplies project-specific roll dimensions, surface options and formulation packages.

It is blended with antioxidant and carbon-black UV stabilizer, produced by extrusion-blowing process. It features high flexibility and ultra-high elongation.<\/p>\n<\/details>\n<details>\n<summary>What is the difference between LLDPE geomembrane and HDPE geomembrane?<\/summary>\n<p>LLDPE has better flexibility, higher elongation and superior low-temperature resistance, suitable for deformable foundation, aquaculture and landfill capping. HDPE is stiffer, with higher tensile strength and stronger chemical resistance, preferred for landfill primary liner, mining heap-leach pads and hazardous-waste projects. HDPE follows GRI-GM13, while LLDPE follows GRI-GM17.<\/p>\n<\/details>\n<details>\n<summary>Can LLDPE geomembrane be textured?<\/summary>\n<p>Yes, co-extruded textured LLDPE geomembrane is available upon custom order under GRI-GM17. Smooth LLDPE is the standard stock item for most projects.<\/p>\n<\/details>\n<details>\n<summary>What are main applications for LLDPE geomembrane?<\/summary>\n<p>Main applications include fish &amp; shrimp aquaculture ponds, landscape lakes, manure lagoons, landfill capping cover, secondary liner, temporary containment ponds, irrigation canals, cold-region anti-seepage projects and biogas floating covers. It is not recommended as primary liner for high-risk heap-leach or hazardous-waste projects.<\/p>\n<\/details>\n<details>\n<summary>What thickness LLDPE geomembrane for fish-shrimp pond?<\/summary>\n<p>0.5 mm-0.8 mm for short-term small ponds; 1.0 mm for medium-large aquaculture projects; 1.5 mm is selected for long-term service and complex foundation conditions.<\/p>\n<\/details>\n<details>\n<summary>Can LLDPE geomembrane be used for landfill bottom primary liner?<\/summary>\n<p>Generally not recommended. HDPE geomembrane (GRI-GM13) is industry standard for landfill primary bottom liner. LLDPE is more suitable for capping cover layer and secondary liner.<\/p>\n<\/details>\n<details>\n<summary>Is LLDPE geomembrane safe for aquaculture?<\/summary>\n<p>Yes. Our LLDPE geomembrane is non-toxic, no harmful substance precipitation, safe for fish, shrimp and aquatic organisms. Smooth surface reduces algae attachment.<\/p>\n<\/details>\n<details>\n<summary>Can LLDPE geomembrane be hot-welded? What welding machines are compatible?<\/summary>\n<p>Yes. LLDPE liner can be welded by hot-wedge welder, extrusion welder and hot air gun. Welding temperature and speed need fine-tuned according to ambient temperature, different from HDPE welding parameters.<\/p>\n<\/details>\n<details>\n<summary>Does LLDPE geomembrane require geotextile protection layer?<\/summary>\n<p>Yes. Geotextile cushion layer is required above and below the liner to prevent puncture by sharp stones and debris, especially for exposed or back-filled projects.<\/p>\n<\/details>\n<details>\n<summary>Can LLDPE geomembrane adapt to uneven and soft foundation?<\/summary>\n<p>Thanks to its high elongation performance, LLDPE geomembrane tolerates differential settlement and soft ground deformation better than HDPE geomembrane.<\/p>\n<\/details>\n<details>\n<summary>What is the service life of LLDPE geomembrane?<\/summary>\n<p>For buried covered condition: service life over 25-30 years. For exposed outdoor condition with UV-stabilized formula: 8-12 years.<\/p>\n<\/details>\n<details>\n<summary>What standard does your LLDPE geomembrane follow?<\/summary>\n<p>Manufactured in accordance with GRI-GM17 specification, test reports including tensile, tear, puncture, OIT, carbon-black content can be provided.<\/p>\n<\/details>\n<details>\n<summary>How is low-temperature performance of LLDPE geomembrane?<\/summary>\n<p>LLDPE keeps good flexibility under low-temperature environment, less prone to brittle cracking compared with HDPE, suitable for cold-climate projects.<\/p>\n<\/details>\n<details>\n<summary>What thickness and width are available for LLDPE geomembrane?<\/summary>\n<p>Available thickness: 0.3 mm-2.0 mm; common sizes:0.5 mm,0.8 mm,1.0 mm,1.5 mm. Standard roll width: 2-8 m. Custom thickness, width and textured version are acceptable.<\/p>\n<\/details>\n<details>\n<summary>What is LLDPE geomembrane price per square meter?<\/summary>\n<p>Price depends on thickness, surface type (smooth\/textured), roll width and total order quantity.
