ECB geomembrane is ethylene vinyl acetate copolymer, through two stages extrusion, three rollers calendering that produce sheet material. It is very similar to EVA geomembrane. The material is translucent body, and it features excellent weather resistance, low temperature resistance, extension rate, impervious, no migration, etc. What's more, it belongs to environmental friendly material. Generally speaking, ECB geomembrane is a compound type product. That is adopt ECB geomembrane sheet and geotechnical cloth to processed into composited geomembrane.
ECB geomembrane is the first choice for the tunnel and dam waterproof projects at home and abroad. Its molecular weight up to 250 thousands. Its good flexibility can meet the requirements of a variety of applications. At the same time, with the advantages of cold resistance, lightweight, elastic, environmental stress cracking properties, it is especially suitable for arch top inner surface waterproof and leakage proof.
