HDPE Smooth Geomembrane for Seepage Prevention Drainage and Protection in Various Field
Product Introduction
Smooth surface geomembrane is an important building material, belonging to one of the geosynthetics. It is mainly used in engineering projects such as impervious, isolation and reinforcement. It is made from high-density polyethylene (HDPE) as the main raw material, with a certain amount of carbon black, antioxidants, anti-aging agents, ultraviolet absorbers and color masterbatches added through a special formula. It is then mass-produced by a highly automated process using a three-layer co-extrusion blow molding technology.
Physical characteristics
The smooth surface of the light-face geomembrane has good reflective ability and heat resistance. In addition, the light-face geomembrane has strong tensile strength and corrosion resistance, which can maintain its original performance and appearance for a long time.
Chemical Properties
The smooth surface geomembrane has extremely low permeability, excellent chemical resistance and UV resistance, which enables it to maintain good performance in various harsh environments.
Green Features
Smooth geomembrane has excellent environmental protection performance. High-quality native plastics and carbon black particles do not contain any preservatives, do not pollute water quality and soil. In addition, smooth geomembranes can be recycled and reused, reducing pollution to the environment.
Product Application
Smooth surface geomembrane can be used for seepage prevention, drainage and protection in water conservancy projects to improve the waterproof performance and stability of the project. In environmental protection projects, it can be used for seepage prevention and protection of landfill sites, sewage treatment plants and other places to reduce pollution to the environment. In the field of construction, it can be used for waterproof and protection of roofs, basements, swimming pools and other places to improve the service life and safety of buildings.
