Why Are HDPE Geomembranes Mostly Black?

- Mar 18, 2021-

The raw material of HDPE geomembrane is high-density polyethylene particles, which are transparent, but in order to ensure that the HDPE geomembrane can resist corrosion and aging in practical applications, black masterbatch with anti-corrosion and anti-aging functions is added. In this way, the HDPE geomembrane is naturally black.

      Moreover, the black HDPE geomembrane also has strong resistance to environmental stress cracking and low temperature resistance, which is much stronger than other colors of HDPE geomembrane.
