is a geomembrane product with a smooth surface on both sides. It is made of high quality high density polyethylene material, which is made of a combination of about 97.5% polyethylene, 2.5% carbon black, a trace amount of antioxidant and heat stabilizer. The resin used in the production process is specially designed for geomembrane. Applied raw polyethylene resin raw materials.
is a geomembrane product that forms a matte surface by nitrogen pressure jetting on the basis of a glossy geomembrane. This process is the only way to produce a matte geomembrane without significantly reducing any of its physical properties. The geomembrane product is made of high quality high density polyethylene material, which is made of a combination of about 97.5% polyethylene, 2.5% carbon black, a trace amount of antioxidant and heat stabilizer. The resin used in the production process is designed for The raw polyethylene resin raw material actually prepared by the geomembrane application.
