Yixing Shenzhou HDPE Geomembrane
HDPE geomembrane liner is the preferred product for lining projects. HDPE liner is resistant to many different solvents and are the most widely used geomembrane liner in the world. Although HDPE geomembrane is less flexible than LLDPE, it provides higher specific strength and can withstand higher temperatures. Its exceptional chemical and ultraviolet resistance properties make it an extremely cost-effective product

Product standards and purchase recommendations of HDPE
·. Implementation standards: National standard GB/T17643-2011, Urban Construction CJ/T234-2006, some scenes need to meet the American standard GRI-GM13.
· Purchase points: Select thickness (0.2-3.0mm) and surface type (glossy/rough) according to project requirements, and give priority to raw material products to improve durability.
HDPE geomembrane has become an irreplaceable environmentally friendly material in modern engineering due to its excellent impermeability, weather resistance and mechanical strength. In practical applications, it is necessary to select specifications based on project requirements and strictly follow construction specifications to ensure long-term stability.
FAQ:
Q: What is a geomembrane used for?
A: HDPE geomembrane is suitable for environmental protection, sanitation, water conservancy engineering, municipal engineering, garden, petrochemical, mining, agriculture, aquaculture, salt industry, hydraulic, transportation, and oil and gas applications as well as in the waste industry.
Q: What are the three types of geomembranes?
A: Geomembrane, as a kind of geosynthetics, is mainly divided into HDPE Geomembrane(high density polyethylene geomembrane) or HDPE liner, LLDPE Geomembrane(line low density polyethylene geomembrane) and PVC Geomembrane(Polyvinyl Chloride Geomembrane).
Q: What are the HDPE geomembrane liners?
A: HDPE geomembrane liners – High-Density Polyethylene geomembrane liners.
Q: What are the types of geomembrane sheets?
A: In terms of material, geomembrane types are divided into HDPE geomembrane sheets and LLDPE geomembrane sheets. In terms of color, geomembrane types are divided into black geomembrane, blue geomembrane, green geomembrane, and white geomembrane. In terms of usage, geomembrane types are divided into aquaculture geomembrane and engineering geomembrane. From the surface, the geomembrane types are divided into smooth geomembrane and rough geomembrane. There are many types of geomembranes, but the main function is to provide support for seepage prevention and environmental protection. Our company is a geomembrane liner company and factory, we can customize geomembrane according to customer needs.
Q: What is the thickness of the geomembrane?
A: Geomembrane Thickness range 0.3mm-3mm.
Q: What is the best thickness for a geomembrane pond liner?
A:0.75mm geomembrane thickness is popular.
Q: Is Geomembrane HDPE waterproof?
