China Geomembrane Manufacturer

Product Description
HDPE (high density polyethylene) geomembrane
Description
The HDPE geomembrane is mainly a high density polyethylene liner made of and high molecular weight, high resistance to ultraviolet rays, 700% coefficient of expansion and high tensile strength. Basically used as impervious barrier to water action, chemicals, petrochemicals, solid wastes (industrial and urban) and mining. So as the storage, conservation for water treatment and aquaculture usage, on very different substrates, as soil, sand, concrete or steel.
General Guide of Installation Quality Control
The PE geomembrane shall be made of high density polyethylene (HDPE) with no change or very low density polyethylene (VLDPE) which does not contain plasticizers, fillers, chemical additives or recycled resins. For UV resistance will be added no more than 2% to 3% of carbon black, allowing the use of chemicals such as antioxidants and stabilizers in temperature, as long as it does not exceed 1.5% or the total. According to the Standar GM-13
The geomembrane shall be supplied in one continuous seamless piece, the max width of rolls is 8 meters wide. The length of the roll must be optimized to make it easy carrying in the field and minimize the number of welds.
The geomembrane may have smooth or textured finish depending on use. The textured geomembrane must be fabricated in order to produce a specified friction in surface irregularities. The thickness of the geomembrane in this case should not include the height of the irregularity of the texturing. According to the standard GM-13.
HDPE Geomembranes smooth or textured shall satisfy the following properties and quality certificates from the resin and control number from each of the rolls supplied.
