LLDPE GEOMEMBRANE-Sichuan Jimu New Technology Co.,Ltd

Product Specifications

LLDPE geomembrane is non-toxic, tasteless, and odorless, with a density between 0.915 and 0.935g/cm3. It is ethylene and a small number of high-grade α-olefins (such as Butene-1, Hexene-1, Octene-1, Tetramethylpentene) -1, etc.) A copolymer is formed by high-pressure or low-pressure polymerization under the action of a catalyst. The molecular structure of conventional LLDPE Geomembrane is characterized by its linear main chain, with only a few or no long branches, but contains some short branches. The absence of long-chain branches makes the polymer more crystalline.
