Polyethylene geomembrane, for example, polyethylene is colorless, but in order to improve the UV resistance of the geomembrane, we usually add carbon black particles, then geomembrane will turn black, and is completely black, after cutting fracture, you will see the complete blackness.Generally, geomembraneare all black. Other colors, such as gray, white, green is formed due to addition of color of coating on black film. There is a certain function, for example, white can reflect lights, drop rising temperature caused by the heat absorption; green film can be used as seal field, more beautiful than a large appearance of darkness.
The color of the geomembrane is mostly black, and also green, white, gray, black green and other colors. The main material of geomembrane is high density polyethylene, auxiliary materials are antioxidants, anti UV agent, carbon black, masterbatch and so on, color of the geomembrane depending on the colour of added masterbatch.
