高密度聚乙烯地膜

We have passed ISO 9000/9001 certification HEPE geomembrane is actually high density polyethylene membrane. Advantages: 1. excellent performance in terms of low temperature protection, 2. resistant to UV light as well as anti-aging 3. chemical resistant to acid/alkli/salt, 4. suitable for a wide range of temperature (-60 +60), 5. life time of up to 50 years old, 6. prominent resistance to environmental stress cracking, 7. minimum permeability. Application: In projects of environmental protection and sanitation: such as rubbish dump, sewage disposal, toxic disposal, hazardous warehouse, workshop etc., In conservancy projects: such as river embankment impermeability, seepage plugging, reinforcement, anti-seepage of water ditch, vertical core wall, slop protection, In projects of municipal engineering: such as subway, underground engineering of architect, water tank on the roof, roof garden impermeability, inner linner of waste water pipe, In projects of garden afforestation: man-made lake, pond, bottom linner in the pond of Golf course, slop protection, In projects of petrochemical plants: such as petrochemical plant, impermeable engineering of oil tank in the oil refinery company, chemistry reactionary pond,inner linner of sediment basin, secondary linner, In projects of mining: impermeable tank and pollution protection tank In projects of traffic facility: road reinforcement, culvert impermeability, In projects of agriculture: such as reservoir, drinking water tank, conservancy pond, impermeability of irrigation system, In projects of aquaculture: inner linner of fish pond and shrimp pond, In projects of polluting enterprises: such as phosphate rock, sugar mill serial No.ItemCH-1CH-21tensile strength(Mpa)higher or equal to 17higher or equal to 252break elongation %higher or equal to 450higher or equal to 5503direct angle tear strength (N/mm)higher or equal to 80higher or equal to 1104carbon black content %higher or equal to 25enviornmental stress cracking resistance F20 (h)higher or equal to6oxidation induction time under 200°C (min)higher or equal to 207vapor permeability coefficient g.cm(cm2.s pa)less then 1.0X10-168low temperature impulse brittleness undr-70°Cqualified9size stability (%)±3
