2 Main uses
PE, EVA geomembrane is a multi-layer co-extruded film (impermeable membrane) and needle-punched geotextile using thermal composite process composite geomembrane (one cloth one film, two cloth one film, two film one cloth) This product has High mechanical strength, aging resistance, strong puncture resistance, large friction coefficient, flexibility, corrosion resistance, etc. At the same time, it has the advantages of light weight, width, low temperature resistance, good water resistance, easy laying and processing, and good weldability. It can be widely used in highway, airport, railway, tunnel, water conservancy, dam, power plant, construction and other projects. It can play the role of reinforcement, isolation, reverse filtration, filtration, drainage, etc., and can extend the life of the project and reduce the maintenance cost of the project. The use of this product is convenient for construction and easy to ensure the quality of the project. PE, EVA geomembrane is a new type of waterproof material. Its material is soft, and it has the best flexibility and low temperature resistance in polyolefins. It is an alternative to PVC impermeable membranes. The outstanding low temperature flexibility of EVA geomembrane is especially suitable for construction in cold areas. Our company can produce EVA geomembrane with different VA content according to the actual needs of users, so that the VA﹪content of EVA co-extruded impermeable membrane is controlled at 5﹪-8﹪ (the higher the VA content, the greater the elasticity and the lower the softening point) ) It is a waterproof and impermeable material made of synthetic resin (HDPE, LDPE, EVA, ECB), etc. as the base material, with the addition of antioxidants, ultraviolet absorbers, color masterbatch and other auxiliary materials.
HDPE geomembrane has good physical and mechanical properties, aging resistance, chemical resistance, weather resistance and puncture resistance.
High elongation of LDPE and EVA, good low temperature performance, soft and easy to construct.
ECB geomembrane is made of ethylene copolymer and petroleum resin, which is a higher grade geomembrane.
Main use edit
HDPE is mainly used in waterproofing projects such as landfills and wastewater treatment plants.
LDPE is mainly used for tunnel composite lining, not suitable for exposed roof.
EVA is mainly used in subway engineering, tunnels, air-raid shelters, dams, artificial lakes, industrial waterproofing and other projects.
ECB is mainly used for waterproofing of subways, roads, dams, tunnels, civil engineering, etc.
The former of HDPE and LDPE is high density, the latter is low density polyethylene
Composite geomembrane, PE geomembrane, EVA geomembrane, reinforced geomembrane, composite geomembrane.
