HDPE geomembrane (USA GRI-GM13 Standards)
HDPE geomembrane is made from high-density polyethylene with added carbon black, antioxidants, anti-aging and anti-UV ingredients. HDPE geomembrane lining is resistant to most different solvents and is the most widely used geomembrane lining in the world.
HDPE geomembrane is made from high-density polyethylene with added carbon black, antioxidants, anti-aging and anti-UV ingredients. HDPE geomembrane lining is resistant to most different solvents and is the most widely used geomembrane lining in the world. It uses the first - class automatic polymer extrusion equipment and three - layer pressing technology. All geomembranes comply with GB, GRI, European and ASTM test standards.
