Product Introduction
HDPE geomembrane, full name of "high density polyethylene geomembrane", is made from high grade polyethylene raw material, adding carbon black, antioxidant, anti-aging and UV-resistance component and is a kind of waterproof and barrier material produced with (medium) high density polyethylene resin as raw material. It has excellent resistance to environmental stress cracking, low temperature resistance, anti-aging and corrosion resistance. It is used for seepage control in domestic refuse landfill, solid waste landfill, seepage control, sewage treatment plant seepage prevention,artificial lake seepage control, etc.
Advantages
1.HDPE geomembrane is a kind of flexible waterproof material.
2.HDPE geomembrane has good heat resistance and cold resistance.
3.HDPE geomembrane high chemical stability, it is a good anticorrosion materials .
4.HDPE geomembrane has the very high tensile strength.
5.HDPE geomembrane has strong anti-aging performance.
6.Spray matte HDPE geomembrane improve the performance of friction on the surface of the geomembrane.
