Introduction

HDPE geomembrane is made of high density polyethylene resin as a waterproof barrier material production. Geomembrane has excellent resistance to environmental stress cracking resistance, low temperature resistance, aging resistance, corrosion resistance, and large temperature range (-60--+60) and long service life (50 years).

Physical properties

1, Excellent chemical resistance, corrosion resistance
2, The outstanding resistance to stress cracking (ESCR);
3, The lowest permeability;
4, UV resistance, excellent;
5, Embrittlement performance of cold resistance of the stable;

Characteristic

1, HDPE geomembrane is a kind of flexible waterproof material, seepage coefficient is very high
2, HDPE geomembrane has good heat resistance and cold resistance, the use of environmental temperature is 110 ° C high temperature, low temperature -70 ° C;
3, HDPE geomembrane has good chemical stability, corrosion resistance to acid, alkali, oil is good anticorrosive material;
4, HDPE geomembrane has a very high tensile strength, so that it has a very high tensile strength can meet the high standards of the project need;
5, HDPE geomembrane has a strong weather resistance, strong aging resistance performance, can long time exposed to use in th sun and maintain the original properties.
6, HDPE geomembrane has strong tensile strength and elongation at break, make HDPE geomembrane can be used in a variety of adverse geological and climatic conditions. To adapt to the geological uneven settlement and strong strain!
