HDPE/LDPE/LLDPE Anti-Seepage Waterproof Geomembrane Transportation for Hydraulic Geotechnical Environmental Project with ASTM

Product DescriptionHigh Density Polyethylene (HDPE) Geomembrane, also known as "High Density Polyethylene Membrane", is a waterproof barrier material made from (medium) high density polyethylene resin. HDPE is a highly crystalline and non-polar thermoplastic resin. HDPE has a milky-white original appearance with a degree of translucency in its thin cross-section.Product features1,It is a flexible waterproof material with a high anti-seepage coefficient.2,It has good heat and cold resistance, and its operating environment temperature is high temperature 110 ºC and low temperature -70 ºC.3,It has good chemical stability and can resist strong acid, alkali and oil corrosion. It is a good anti-corrosion material.4,It has high tensile strength, which enables it to meet the needs of high standard engineering projects.5,It has strong weather resistance, strong anti-aging performance, and can be exposed for a long time to maintain the original performance.6,Having strong tensile strength and elongation at break, HDPE geomembrane can be used in various harsh geological and climatic conditions. Strong adaptability to geological uneven settlement strain.7,Made of high-quality native plastic and carbon black particles without any preservatives. Technical indexOrdinary HDPE Geomembrane:                                                         GB/T 17643-2011No.ItemIndexThickness,mm0.30 0.50 0.751.00 1.251.50 2.00 2.50 3.00 1Density,g/cm2>=0.9402Tensile yield strength (longitudinal and transverse),N/mm>=4>=7>=10>=13>=16>=20>=26>=33>=403Tensile breaking strength (longitudinal and transverse),N/mm>=6>=10>=15>=20>=25>=30>=40>=50>=604Elongation at yield (longitudinal and transverse),%--->=115Elongation at break (longitudinal and transverse),%>=6006Right angle tear load (longitudinal and transverse),N>=34>=56>=84>=115>=140>=170>=225>=280>=3407Puncture resistance,N>=72>=120>=180>=240>=300>=360>=480>=600>=7208Carbon black content,%2.0~3.09Carbon black dispersibilityNo more than 1 level 3 of 10 data, and levels 4 and 5 are not allowed.10Atmospheric pressure oxidation induction time(OIT),min>=6011Low temperature impact embrittlement performancePass12Water vapor permeability coefficient,g·cm/(cm2·s·Pa)
