HDPE Geomembrane
Anuncio
Geomembrane HDPE Polyethylene Geomembranes are specifically designed for exposed conditions. They do not contain additives or filling that could evaporate and deteriorate the material in time. Geomembranes are generally applied as watertight elements to contain liquids, as leach pad lining, and in dumps, canals, water-collecting areas and reservoirs. Polytex Geomembranes can be heat-sealed and are made of especially formulated and certified virgin polyethylene resins. They are resistant to a number of chemical products including acids, salts, alcohols, oils and hydrocarbons, concentrated or diluted at different temperatures. Besides their high resistance to chemical agents and UV (2-3% carbon black), they show outstanding mechanical properties: high tensile strength and great rigidity, and their extremely low impermeability makes them an excellent barrier to fluids and gases. High Density Polyethylene (HDPE) Geomembranes Available in both smooth and textured surface, 0.5-3.0 mm thick, a maximum of 8.5 m wide, and length according to requirements. Textured surface films provide great friction resistance. Colored geomembrane is also available upon request. Textured asperity can also be manipulated to meet project needs.

Linear Low Density Polyethylene (LLDPE) Geomembranes Available in thickness of 0.5-2.5mm, a maximum of 8.5 m wide, and length according to requirements. Minimum density of 0.939gr/cm3 makes it flexible enough to adhere to steep slopes. Polytex is producing co-extruded LLDPE, alloyed LLDPE, and hybrid LLDPE products to meet the challenges that fabricators, mining, and landfill caps require. These products range in thickness from .2 mm to 2.5 mm and up to 10 m wide rolls. Inquire at Polytex for its product group consisting of floating covers, films for fabricators, or thermal films used in mining applications.
