PE and EVA geomembranes are composed of multi-layer co-extruded films (impermeable membranes) and needle-punched geotextiles using thermal composite technology to composite geomembranes (one cloth and one film, two cloth and one film, two films and one cloth). It has the characteristics of high mechanical strength, aging resistance, strong puncture resistance, large friction coefficient, flexibility, corrosion resistance, etc., and also has the advantages of light weight, wide width, low temperature resistance, good water resistance, easy laying and processing, and good weldability. Can be widely used in highways, airports, railways, tunnels, water conservancy, dams, power plants, construction and other projects. It can play the role of reinforcement, isolation, reverse filtration, filtration, drainage, etc., and can prolong the life of the project and reduce the maintenance cost of the project. The 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, its flexibility and low temperature resistance are the best among polyolefins, and it is a substitute for PVC impermeable membrane. The outstanding low-temperature flexibility of EVA geomembrane is especially suitable for construction in cold regions. Our company can produce EVA geomembranes with different VA content according to the actual needs of users, so that the VA﹪ content of the EVA co-extruded anti-seepage membrane is controlled at 5%-8﹪ (the higher the VA content, the greater the elasticity and the lower the softening point ) is a waterproof and anti-seepage material made of synthetic resin (HDPE, LDPE, EVA, ECB) as the base material, adding antioxidants, ultraviolet absorbers, masterbatches and other auxiliary materials.
