It is manufactured from HDPE resin blended with titanium dioxide (TiO\u2082), antioxidant and light stabilizer via extrusion or co-extrusion process. Different from black geomembrane using carbon-black for UV absorption, white geomembrane reflects solar radiation to keep lower surface temperature. Defects, holes and welding seams are easy to detect by visual inspection.Titanium-dioxide pigment provides less native UV protection than carbon-black. UV-stabilized formulation is mandatory for long-term exposed service. Buried service life is comparable to black HDPE geomembrane.<\/p>\n<h2>Key features<\/h2>\n<ul>\n<li>Reflects solar radiation and can reduce surface temperature by 10-25\u00b0C versus black liner<\/li>\n<li>Makes holes, scratches and weld defects easier to identify during inspection<\/li>\n<li>White-on-black construction reveals the dark core when the surface is damaged<\/li>\n<li>Clean appearance for potable-water reservoirs, landscape ponds and visible installations<\/li>\n<li>HDPE substrate provides strong mechanical and chemical resistance<\/li>\n<li>Compatible with hot-wedge, extrusion and hot-air welding equipment<\/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\">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>\u22650.940<\/td>\n<td>ASTM D1505<\/td>\n<\/tr>\n<tr>\n<td>Elongation at Yield<\/td>\n<td>%<\/td>\n<td>\u226512<\/td>\n<td>ASTM D6693 (Type IV)<\/td>\n<\/tr>\n<tr>\n<td>Elongation at Break<\/td>\n<td>%<\/td>\n<td>\u2265700<\/td>\n<td>ASTM D6693 (Type IV)<\/td>\n<\/tr>\n<tr>\n<td>Stress-Crack Resistance (SP-NCTL)<\/td>\n<td>h<\/td>\n<td>\u2265500<\/td>\n<td>ASTM D5397<\/td>\n<\/tr>\n<tr>\n<td>Standard OIT<\/td>\n<td>min<\/td>\n<td>\u2265100<\/td>\n<td>ASTM D3895<\/td>\n<\/tr>\n<tr>\n<td>High-Pressure OIT (HP-OIT)<\/td>\n<td>min<\/td>\n<td>\u2265400<\/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\">0.75 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\">2.5 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>11<\/td>\n<td>15<\/td>\n<td>22<\/td>\n<td>29<\/td>\n<td>37<\/td>\n<td>ASTM D6693<\/td>\n<\/tr>\n<tr>\n<td>Tensile Break Strength<\/td>\n<td>kN\/m<\/td>\n<td>20<\/td>\n<td>27<\/td>\n<td>40<\/td>\n<td>53<\/td>\n<td>67<\/td>\n<td>ASTM D6693<\/td>\n<\/tr>\n<tr>\n<td>Tear Resistance<\/td>\n<td>N<\/td>\n<td>93<\/td>\n<td>125<\/td>\n<td>187<\/td>\n<td>249<\/td>\n<td>311<\/td>\n<td>ASTM D1004<\/td>\n<\/tr>\n<tr>\n<td>Puncture Resistance<\/td>\n<td>N<\/td>\n<td>240<\/td>\n<td>320<\/td>\n<td>480<\/td>\n<td>640<\/td>\n<td>800<\/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>Potable-water reservoirs and clean-water regulation basins<\/li>\n<li>Landscape ponds, fountains and ornamental artificial lakes<\/li>\n<li>Mining evaporation ponds and exposed solution-holding basins<\/li>\n<li>Landfill capping covers requiring reduced thermal stress and easier inspection<\/li>\n<li>Temporary water containment and emergency cofferdams<\/li>\n<li>Industrial basins where a light-colored liner improves liquid-level and defect visibility<\/li>\n<\/ul>\n<h2>Specification and supply<\/h2>\n<p>Taiji supplies project-specific roll dimensions, surface options and formulation packages.

Two common types: full-white and co-extruded white-on-black (white top surface, black HDPE core). It complies with GRI-GM13 standard. Unlike black geomembrane using carbon-black for UV protection, white geomembrane reflects sunlight.<\/p>\n<\/details>\n<details>\n<summary>What is the difference between white and black HDPE geomembrane?<\/summary>\n<p>Black HDPE uses carbon-black for excellent inherent UV resistance, suitable for long-term exposed landfill and mining projects. White HDPE uses titanium dioxide to reflect solar radiation, resulting in lower surface temperature and easy visual inspection. Its native UV resistance is weak; special UV-stabilized additive is required for outdoor exposed application. Mechanical performance is identical under same thickness.<\/p>\n<\/details>\n<details>\n<summary>Can white geomembrane be textured?<\/summary>\n<p>Yes. Smooth, single-sided textured and double-sided textured white HDPE geomembrane are available by co-extrusion technology.<\/p>\n<\/details>\n<details>\n<summary>What are main applications of white HDPE geomembrane?<\/summary>\n<p>Main applications: potable-water storage reservoirs, landscape artificial lakes, mining evaporation ponds, landfill capping cover, temporary containment ponds, industrial observation ponds. It is not recommended for primary liner of hazardous-waste and high-risk heap-leach projects without special formulation validation.<\/p>\n<\/details>\n<details>\n<summary>Is white geomembrane safe for drinking-water pond?<\/summary>\n<p>Yes. Food-grade formulation white HDPE geomembrane has no color leaching, suitable for potable-water storage projects. Please specify drinking-water grade while placing order.<\/p>\n<\/details>\n<details>\n<summary>Can white geomembrane be used for long-term fully-exposed outdoor condition?<\/summary>\n<p>Ordinary white geomembrane cannot sustain long-term direct UV exposure. UV-stabilized modified formula is mandatory for exposed projects. Buried covered installation does not require special UV modification.<\/p>\n<\/details>\n<details>\n<summary>Why choose co-extruded white-on-black geomembrane?<\/summary>\n<p>The white top layer provides low-temperature and visual-inspection advantage. Once surface is scratched or punctured, the black core will be exposed, making damage easy to spot during construction and maintenance.<\/p>\n<\/details>\n<details>\n<summary>Can white HDPE geomembrane be hot-welded? Which welding machines are compatible?<\/summary>\n<p>Yes. Weldable with hot-wedge welder, extrusion welder and hot air gun. Welding parameters are similar to black HDPE geomembrane; fine-tune temperature according to actual site ambient temperature.<\/p>\n<\/details>\n<details>\n<summary>Does white geomembrane need geotextile protection layer?<\/summary>\n<p>Yes. Same as black HDPE geomembrane, geotextile cushion is required above and below liner to avoid puncture by sharp stones and debris.<\/p>\n<\/details>\n<details>\n<summary>What is the service life of white HDPE geomembrane?<\/summary>\n<p>Buried covered condition: over 30 years. UV-stabilized formula for exposed condition: 10-14 years. Ordinary white geomembrane without UV additive is not suitable for exposed service.<\/p>\n<\/details>\n<details>\n<summary>What specification does your white HDPE geomembrane follow?<\/summary>\n<p>Complies with GRI-GM13 standard. Test reports for tensile, tear, puncture, OIT can be provided upon request.<\/p>\n<\/details>\n<details>\n<summary>How much lower is the surface temperature of white geomembrane compared with black geomembrane under sunlight?<\/summary>\n<p>Under strong sunlight, white geomembrane surface temperature can be 10-25 \u2103 lower than black HDPE liner, effectively reducing thermal stress and wrinkle risk.<\/p>\n<\/details>\n<details>\n<summary>What thickness and width are available for white HDPE geomembrane?<\/summary>\n<p>Thickness range:0.5-3.0 mm; common sizes:0.75 mm,1.0 mm,1.5 mm,2.0 mm. Standard roll width:2-6 m. Full-white \/ co-extruded white-on-black, smooth\/textured versions are customizable.<\/p>\n<\/details>\n<details>\n<summary>What about the price of white HDPE geomembrane per m\u00b2?<\/summary>\n<p>Price varies by thickness, surface type, full-white or co-extruded structure, UV-stabilized requirement and total order quantity.
