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:
