LLDPE geomembrane Features

  1. High anti-seepage coefficient—LLDPE geomembrane has an anti-seepage effect that ordinary waterproof materials can’t match. LLDPE geomembrane has high tensile mechanical resistance, and its excellent elasticity and deformability make it very suitable for expansion or contraction of the base surface, which can be effective To overcome the uneven settlement of the base surface, the water vapor permeability coefficient K<=1.0*/c cm2.
  2. Chemical stabilityGeomembrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction tanks, and landfills. High and low-temperature resistance, asphalt, oil and tar resistance, acid, alkali, salt, and more than 80 kinds of strong acid and alkali chemical media corrosion.
  3. Anti-aging performance—LLDPE geomembrane has excellent anti-aging, anti-ultraviolet, and anti-decomposition capabilities, and can be used in the open. The service life of the material is 50-70 years, which provides a good material guarantee for environmental seepage prevention.
  4. Resistance to plant roots—LLDPE geomembrane has excellent puncture resistance and can resist most plant roots
  5. High mechanical strength-geomembrane has good mechanical strength, tensile strength at break 28MP, elongation at break 700%
  6. Low-cost and high efficiency—LLDPE geomembrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the production cost is lower than traditional waterproof materials. According to actual calculations, general engineering using LLDPE geomembrane should be saved Costs around 50%
  7. Fast construction speed—geomembrane has high flexibility and has a variety of specifications and multiple laying forms to meet the anti-seepage requirements of different projects. It adopts hot-melt welding, high weld strength, convenient construction, fast and healthy.
  8. Environmental protection and non-toxic—The materials used in the geomembrane are all non-toxic and environmentally friendly materials. The anti-seepage principle is ordinary physical changes and does not produce any harmful substances. It is the best choice for environmental protection, aquaculture, and drinking water ponds.

GEOFANTEX has an on-site Manufacturing Quality Assurance Laboratory at the factory. GEOFANTEX maintains a high level of quality and up-to-the-minute results on finished products through a fully equipped, well-staffed, dedicated laboratory existing in each of the manufacturing facilities. Each facility follows the same guidelines for evaluating the quality of GEOFANTEX products and is capable of adapting to market-driven requirements.
A. Objective
The objective of the GEOFANTEX Quality Assurance program is to define the implementation of basic manufacturing quality assurance (MQA) procedures necessary to ensure the consistent production of quality products supplied to the geosynthetic market. Note that at this time, these procedures are limited to polyethylene geomembrane.
B. Scope
In order to achieve GEOFANTEX’s stated purpose, a rigorous set of minimum standards and an effective test program to assure compliance have been established. These procedures and requirements are frequently reviewed and adjusted to assure compliance with current market demands and/or predetermined project specifications. These procedures assure that raw materials and process parameters are controlled to provide products complying with GEOFANTEX’s pre-defined minimum characteristics.


A. Roll Numbering

Each roll of geomembrane is assigned a unique roll number. The Quality Assurance Laboratory maintains records documenting the raw materials and resulting product quality information.

B. Approval Procedure

Results for each tested roll of the product are checked against both GEOFANTEX China standard and customer specifications for compliance. The Quality Assurance Laboratory approves those materials that meet these requirements for shipment.

C. Non-Conformance

Material that does not meet GEOFANTEX minimum standards is given a roll number but is rejected and not placed into inventory. The material is identified as scrap and will not be utilized. Material that meets GEOFANTEX minimum standards but does not meet a stricter customer specification is not allocated to that customer but is placed into inventory as GEOFANTEX standard material.

D. Documentation

Individual Quality Assurance Certificates are generated and supplied for each roll of geomembrane product to include all relevant quality assurance information about the material(s).

What is LLDPE Geomembranes – GeofanMeb® LLD

LLDPE geomembrane is made of plastic roll material, and its LLDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original LLDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene), and hydrogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance. LLDPE has good anti-corrosion performance, electrical performance, moisture-proof performance, anti-leakage performance, and high tensile strength, so it is very suitable for wire and cable, engineering anti-seepage, breeding anti-seepage, oil tank anti-seepage, basement anti-seepage, artificial Lake seepage prevention, and other fields. LLDPE geomembrane has excellent impact resistance, so it is the same at normal temperature and even at low temperatures of -40F. LLDPE geomembrane is a non-toxic, odorless, and odorless white particle of high molecular polymer. The melting point is about 110℃-125℃, and the relative density is 0.918~0.935g/cm3. It has good heat resistance and cold resistance. Good chemical stability, high rigidity, and toughness, good mechanical strength, environmental stress cracking resistance and tear resistance strength performance, as the density increases, the mechanical properties, and barrier properties will increase accordingly, heat resistance, and tensile strength The strength is also higher; it is resistant to corrosion by acids, alkalis, and organic solvents.
